like this:
var foo = 45;
var bar = '' + foo;
Actually, even though I typically do it like this for simple convenience, over 1,000s of iterations it appears for raw speed there is an advantage for .toString()
See Performance tests here (not by me, but found when I went to write my own): http://jsben.ch/#/ghQYR
Fastest based on the JSPerf test above: str = num.toString();
It should be noted that the difference in speed is not overly significant when you consider that it can do the conversion any way 1 Million times in 0.1 seconds.
Update: The speed seems to differ greatly by browser. In Chrome num + '' seems to be fastest based on this test http://jsben.ch/#/ghQYR
Update 2: Again based on my test above it should be noted that Firefox 20.0.1 executes the .toString() about 100 times slower than the '' + num sample.

In my opinion n.toString() takes the prize for its clarity, and I don't think it carries any extra overhead.
How does computer or programming languages out there converts binary integers into a string? what is the algorithm behind it? Like int 300 to string "300"
Hey, all. I was working on some Codewars fundamentals and I came across this problem. My solution was accepted and, on the list of acceptable solutions, I see what seems to be an equally useful solution. I just wondered if there's any reason to use one over the other in any particular situation or if they do the same thing all the time. The passed in variable was some integer num.
My solution was:
return Integer.toString(num);
The other solution I saw was:
return String.valueOf(num);
Any insight would be much appreciated. Thanks!
