can javascript run faster?

[totally beginner]

i have a javascript code that huge enough (because so many loop & create new element ).

does anyone know how to make a javascript program can run faster?

does anyone know/have program that can simplify my javascript program (maybe a program that automatically remove something not important in javascript code like remarks & indentation) so my javascript program's size can be smaller and faster to load from internet?

avoid nested loops, recursive stuff and do your comparisons of arrays on sorted arrays instead of n^2 comps.

ie: code better.

Are you collecting info from a form?

If so you could maybe try collecting some of the information using a server side script first and then using this information to reduce the amount of javascript that you need to run?

maybe you can post your code here, we'll see what can be done to improve it

I have noticed that javascript doesn't scale that well. If your arrays start to get pretty big, the client machine wil choke. I also agree with the loops and nesting.
