I'm a software engineer on the Chrome Team.

Thanks for tearing yourself away from lunch

So like I said, I'm an engineer on the Chrome Team,

I spent a lot of my life working in JavaScript.

I joined the Chrome Team from a web development background,

specifically working on open source JavaScript tool kits

working web application development and security.

I spent most of my day trying to figure out

how to make JavaScript do interesting things.

My personal history with JavaScript started in 1997,

I think when a lot of us started to be cognizant of the web.

And at the time, JavaScript was this thing

and somewhat widely available on the back of the browser wars.

how we got to where we are today with JavaScript,

to figure into the sorts of things we try to do

And I want to take you through what's really

that makes it so different to the languages

that you might be using in your day-to-day work

that aren't JavaScript, because there's a lot that is.

an ambiguous question, right? If you're a browser bender,

it's easy to say we're this fast--easy-ish.

but that doesn't necessarily tell you anything

And I want to spend a lot of time today talking about

how it is that we are going to get a different future

and help you understand exactly what's going on

and how these parts relate to each other, because they do.

and the current state informs what's going to happen next.

So how many of you write in other functional languages

or are familiar with functional languages?

The front of this talk is going to be something

that maybe just warms your heart and may not be new information.

In the sort of the history of functional languages,

it's got this nice first class function system,

and in 1995, Brenda and I hacked it up as a little prototype

to really have any serious scripting supported.

because the W3C wasn't the place for languages.

And in 1997, we got the first version of JavaScript

and that was the first version of JScript.

Nobody knew how big the web was going to be,

Today, you can't ship a credible platform

was finalized at TC39, which is the technical committee

that is the standards body for JavaScript.

as Mocha/LiveScript/JavaScript in Netscape 2,

JavaScript 3, ECMAScript 262-3, the version or the standard

that was released in 1999 has powered us pretty much to today.

It has been the thing that for more than a decade

And JavaScript, on the back of that standard,

JScript, the component that runs JavaScript inside of IE,

has been built in to the OS for Windows since Windows 98.
