How to avoid blocking the execution of JS code?

Question

JavaScript

How can we avoid blocking script execution if we currently have some complex processing going on?

Answer 1

JS is single-threaded, so in a normal situation you won't be able to do this. Any complex calculation will block script execution for some time. Therefore, the only solution is to move the calculation to another place. Web workers are used for this (as colleagues have pointed out). But unfortunately the technology is relatively new and you can't do anything in IE < 10

Answer 2

Worth a look at web workers. https://developer.mozilla.org/en/docs/DOM/Using_we...
