Writing Efficient JavaScript
This talk walks through several techniques for speeding up JavaScript. The information is a presentation of the topics discussed in my chapter for the book, Even Faster Web Sites. Topics include:
- Managing scope – learn why scope is important and how to manage it for optimal performance.
- Data access – learn what types of data access take longer in JavaScript and how to mitigate their effects.
- Flow control – learn how to use “if” statements and loops efficiently.
- Avoid long-running scripts – learn what causes the browser to stop executing your code and what to do to avoid it.
