expression to find highest number in array

[søren kristensen]

I feel this should be very simple, but I can’t find the solution. I need an expression that determines which number in an array is the largest.

Hi Soren

Let’s say tmpArr is your array, so you can loop through it and find the biggest one:

var biggestNum = tmpArr[0];
for(var i = 1;i < tmpArr.length;i++){
    if(biggestNum < tmpArr[i]){biggestNum = tmpArr[i]}
}

Cheers!

A bit simper one:

numArray = [1,10,5,3]

Math.max.apply(null, numArray)

Very nice!! could you explain a little bit why it does work?

I was stuck trying to do it like that:

numArray = [1,10,5,3]

Math.max(numArray);

You saved me
