Javascript

since 1995 (earliest usage recorded on this site was 1993)

JavaScript is an object-oriented scripting language used to enable programmatic access to objects within both the client application and other applications. It is primarily used in the form of client-side JavaScript, implemented as an integrated component of the web browser, allowing the development of enhanced user interfaces and dynamic websites. JavaScript is a dialect of the ECMAScript standard and is characterized as a dynamic, weakly typed, prototype-based language with first-class functions.

cdeblois

1993–

Exposed to this before I ever used it. Didn't end up really using this until 2003.

coordt

1993–2010

I can remember when it was called LiveScript. Damn I'm old.

mjhagen

1993–

boutell

1994–

This morning I used the phrase "bare-metal JavaScript" in email and then burst out laughing. jQuery makes things good. I've written a nice multiple select element progressive enhancer which is included in Apostrophe.

dasil003

1994–

Incredible that I used this language in a cut-and-paste, trial-and-error fashion for over a decade before considering that maybe I should really learn how it worked. Much love to Douglas Crockford for showing the elegance of Javascript to the programming world.

zeroaltitude

1995–

Javascript is the new Lisp in the following sense: it is the most accessible introduction to Functional Programming that a programmer is likely to get outside of an academic program.

bitprophet

1995–

Started using it shortly after discovering HTML and continue to dabble as necessary. Never been a power user, though.

1995–

1995–

1995–

Since it was called LiveScript - oh, those heady days of waiting for Netscape betas to download…

1995–

1995–

1996–

1996–

This is the first programming language that I deployed anything for the rest of the world to see. I did some crazy cool things with the status bar back in the day. :-)

jamesotron

1996–

Started using her for what was then called 'DHTML' and now is just called HTML. She is all talk no action.

xurizaemon

1996–

At first I didn't know better, and got away with more than I deserved. She grew up and turned into something entirely more lovable. We're still close friends.

greyfade

1996–

Discovered web development

jdunck

1996–

I learned JavaScript, such as it was, in IE3 when I tried to convince a team to switch from VBScript. We had no idea what we were doing with JavaScript at the time...

Used it since it appeared in Navigator, and also server-side in the Netscape server (remember that?) Only recently started to care for it, thanks to JQuery

chl

1997–

Don't even remember when I first used JavaScript. In any case, it's been one of my most-used & -loved languages since I got into Helma ~2000.

wilane

1997–

Well, I need it all the time. jQuery, Dojo and alike made it more enjoyable

nowells

1997–

Javascript has been a constant source of experience since I started working on the web in 1997

1997–

1997–

1997–

1997–

1997–2000

Never did JS in the browser, but I did it for a few years server-side in a NetImpact Dynamo-based server. Everything old is new again.

mpirnat

1997–

It makes me weep, but I keep coming back to it.

xhae

1997–

Love-hate relationship.

stephen_mcd

1998–

One of my favourites - incredibly powerful once fully understood

LorenDavie

1998–

I love it. I hate it. I love it. I hate it.

carljm

1998–

Not much of a choice; if you do web work, you have to know Javascript. I started back when it was called "DHTML" and if you were doing anything serious, you pretty much had to pick your target browser first.

lukeman

1998–

My usage of Javascript these days is a bit more substantive, as those early days mostly meant copying and pasting some menu script and making alterations.

kcunning

1998–

pmclanahan

1998–

When combined with jQuery, it's pretty great.

soryu2

1998–

JS has seen a great revival and will continue to step into the limelight. With Apple & Google pushing hard to make it extremely fast and node.js & capuccino et al there is a lot of potential.

pydanny

1998–

Mostly have used it in short periods of high intensity. Like everyone else, I have a love/hate relationship. YUI leaned me more towards love and JQuery even more so.

bg4

1998–

Both for the web and used ECMAScript with VXML applications I was working on around 2004. Nowadays it's Prototype, YUI etc.

benjaminws

1998–

Heh, heh

bittercoder

1998–

I started with very basic javascript (form validation anyone) during my time studying. Javascript skillls have grown slowly by surely every year since.

1998–

1998–

1998–

1998–

1998–

Started doing Javascript when I first learned HTML as a kid. Re-discovered JS all over again in 2003-04 thanks to AJAX and the whole web2.0 phenomenon.

binarydud

jcarbaugh

paulsmith

Used to despise it, not understand it, now it's pretty nifty, Lisp-y, fast, and widely deployed. Thanks, whomever!

westonruter

1999–

My favorite language. Excited for it to become ubiquitous on the serer as is it is on the client with the CommonJS initiative.

CerealBoy

1999–

undoingemptyvoid

1999–2010

Used it most recently for a slide show based on JQuery and for some enhancements of Rails pages. Don't use it daily.. monthly.

doughellmann

1999–

bkmontgomery

1999–

I'm a web developer. I use it as needed for that purpose.

davisagli

1999–

Implemented a fricking cross-browser compatible drag-and-drop layout system in the days before Javascript debuggers.

lambacck

One day we won't need you anymore. Today is not that day.

1999–

2000–

A beautiful, very powerful scripting language.

jefftriplett

2000–

Use Javascript enough to build / maintain some client form processing scripts then rarely if ever had to touch it again. Reusable code FTW! I flirt with jQuery as time permits now.

nathans

2000–

First learned for home pages.

AndyC

2000–

growe

2000–2005

Seemed a horribly clunky language with no relation to Java that I could see. Hated it.

justinlilly

2000–

Started when I really got into real web development. Only recently (late 2009, early 2010) gotten into server-side js.

k_wade_a

2000–

deep

2000–2010

mwarkentin

2000–

Started hacking around with it for image rollovers back in the early part of the decade. It's now a huge part of my job, and thankfully much more useful these days.

sanchom

2000–2002

Used for simple DHTML to add dynamic elements to a early, hand-made blog.

maxlynch

2000–

jasonb

2000–2004

pain

jjames

2000–

I don't know if it is fair to say I completely understood the power of javascript when I first learned it (or that I do even yet). I am constantly amazed and confused by both its elegance and warts. I love them both.

johnny723

2000–

Couldn't really remember when exactly I learn JavaScript ... I was teaching it in lectures from 2005-2009 but recently dropped it.

bhaugen

2000–

Got deepest doing both client and server-side JS for JotSpot. Nice to use same language on both sides, but still an impedance mismatch.

Josh

2000–

twhitton

2000–

Honestly, I've never really learned Javascript. I generally crib just enough information from Google to limp up and down the DOM. I know it has all kinds of nifty functional features and a bright future ahead. One day I will give it its due.

2000–2010

Some day they will get it right...

Flamer

2001–

robhudson

2001–

Wrote some very bad Javascript in the early web dev days. I feel much more comfortable with the language as a whole these days, and love that there are frameworks to hide the ugly parts.

smalltobi

2001–

In the beginning I didn't really like it. Since I discovered the object oriented nature of it I like it more and am using it extensively for RIA's.

thumper

2001–

It took me a while to get into web development.

2001–

2002–

Actively using both in commercial and hobby projects.

Zak

2002–

I can't remember when I actually first used JS, but I'm sure I used it for real work in 2002. I almost like it; shame about the syntax.

ShawnMilo

2002–

I started using JavaScript while working with ASP. Before AJAX was an acronym I wrote some heavy client-side functionality to simulate the same effect. These days, though, I usually just use jQuery for everything I can.

2002–

Silly DHTML stuff to begin with, proper use via jQuery and deeper understanding of language today.

mrtrosen

mikl

2003–

Very powerful and useful for webprogrammers.

metavida

2003–

ntoll

2003–

Started out as a PIA (mainly due to the browsers) but I've recently really been loving Javascript.

davidpaccoud

2003–

Used for DOM manipulation and hated it until I discovered jQuery. Recently learned its inheritance model and plan to test it for server side programming.

2003–

2003–

First prototype, now jQuery.

fdrake

The web thing. Always a source of great pain, though quite useful in practice.

vbabiy86

2004–

brosner

2004–

jQuery and Node.js are great tools.

2004–

2004–2010

CoffeeScript FTW

sdhamilton

2004–

Used before my undergrad degree, calling it from html attributes, awful! Using JQuery now and as little as possible, consistent support it not great.

ch0llima

2004–

First looked at it in 2004, never got that good with it though.

trey

2004–

sli

2004–

Rgoodermote

2004–

If only that 2004 meant something, I'm still an idiot when it comes to this language.

2004–

2004–

2005–

2005–

2005–

used some silly stuff in the beginning. Now try to only use with jquery - if Python ran embedded in the browser, would not bother

kratorius

sebleier

2005–

natevw

2005–

Proud to say that my first Javascript project was to make our wedding's save-the-date page look Flash-based without Flash.

sbastn

2005–

Started with prototype with Rails, then did some JQuery and I am now exploring Raphael. But guess what? This year I am going to learn the real javascript, not the frameworks. I promise

andrew

2005–

If you are developing for web, you need to know this language

edfuh

2005–

baller

ericflo

2005–

msnaith

2005–

I can manipulate the DOM with relative ease, although anything I use it for can now be done a lot cleaner with frameworks such as jQuery.

fogus

2005–

streetcleaner

2005–

A beautiful language.

aburkhalter

2005–

CrociDB

2005–

jmillikin

2005–

Buried somewhere below the layers of bad ideas is a beautiful, Scheme-like language. If written with caution and restraint, can be fun to work with.

2005–

2005–

2005–

2005–

2005–

A good way to manipulate a web document, or even create complex web 2.0 applications. Somewhat loose rules, but quite simple. I like the jQuery framework.

2005–

2005–

2005–

2005–

2005–2008

Took an interest in this back during my first year of programming. I never used it in browsers; rather, I used it in a JS-based game engine called Sphere.

jeremybowers

2005–

Javascript frameworks are the best.

fourplusone

2006–

shywolf9982

2006–

I started using it heavily when I started with web developement. Took me a good two months to discover prototyping. Took me two years more to fully get it. I'm nowadays on decent terms with it, although I can't imagine doing a full blown application with it.

gsiegman

2006–

A major goal of mine is to drastically improve my skills with this language.

newmaniese

The Good Parts

GordyBrow

2006–

A relaly useful language to be able to use when doing any web work.

I've only dabbled a bit, but can usually bend it to my will.

vrejohanian

2006–2009

It's useful but... i need a practice !!

d3f3nd3r

adambrenecki

2006–

First started tinkering with JS when I needed some client-side stuff in a PHP app, I've only started using it properly in the last 2-3 years.

collypops

2007–

Picked this up to contend in my university's Hackday. Been using it heavily ever since.

madewulf

2007–

The language is fun, but the implementations in the browsers made it a pain to use... until I discovered JQuery. It was a breeze to learn JavaScript after using ActionScript for some months (which is basically the same language).

qwertymz

2007–2009

Fun stuff. Need to get back in there.

It does nothing to encourage anything but fugly code (especially with jQuery and it's ghastly nested anonymous functions) but a definite case of ends justifying the means.

Not being a web programmer, I've only made occasional use of it. I'm much better at hacking someone else's JS than writing it from scratch.

Used it heavily in the form of Adobe Illustrator scripting during 2007-2008. Can't say I really got into it until I started playing with OpenSocial in 2009. Then I discovered jQuery and was hooked.

Tried to stay away from it all the time. But jQuery took me into it. It is an amazing language I've learned. Currently, the second most favourite language of mine.

Used it a bit to do light form submission and a bit of AJAX for university and work, not really a fan of it.

Sure, I used Javascript, but I never understood it until two years ago. This is only because I started using jQuery. So, no, I've never worked with raw Javascript, but this is as close as I'm going to get to it.

Quite a simple yet also interesting language. It is simple in appearance yet powerful inside.

Hated it at the turn of the millenium. But you have to know it for web dev today.

Honestly I can't say if I "know" JavaScript or not. I think it's similar to what I've heard about Scheme in that you can just do /so/ much with it because of the way that it's structured. Even though I've found one approach that works for me I still don't understand all the different ways that you can apply it.
