Memory leak in JavaScript (Chrome)

Question

I\'m calling a function 50 times a second, which does some expensive things as it is painting alot on a element.

It works great, no problems

Answer 1

Look at heap profile under the Profiles tab in Chrome's developer tools for information about memory usage.

You can do the following to prevent memory leaks:

• Test your code with JSLint, to see if that will give you some pointers.
• Use the var keyword to give your variables function scope, so they can be garbage collected when they go out of scope. Without the var keyword variables have global scope.
• Use delete variable; statements to remove the object as well as the reference from memory. Setting the variable to null will only remove the object from memory, but not its reference.
