Could this be a Repeat Question?
Discussion on faster loops: while vs. for
In the world of three.js, I have noticed a common code pattern that exists in various programming languages:
for ( var i = 0, l = something.length; i < l; i++ ) {
perform some actions using index i
}
However, I have come across information suggesting that in JavaScript, performance could potentially be improved by utilizing:
var i = something.length;
while(i--){
perform some actions using index i
}
Does implementing this alternative approach actually result in noticeable performance enhancements? Is there a clear advantage to choosing one method over the other?
