How to Speed Up Your JavaScript!

Speaker: Nicholas C. Zakas

As an interpreted language, JavaScript is filled with hidden performance issues that conspire to slow down your code and ruin the user experience. Learn exactly what is fast, what is slow, and what you can do to squeeze that last bit of performance out of your JavaScript code.

Notable Quotes:

“The problem is that JavaScript is slow… And the secondary problem is that people notice that it’s slow, because a lot of the web is about perceived performance. If your is slow and people perceive it to be slow, then you're in a lot of trouble."

"Really the issue is, browsers aren't going to help you with your code. They don't care that your code is running slow, they're not going to do anything to adapt for it. So really, if something has to be done to speed up your code, it pretty much has to be done by you."
