JavaScript：非常大的数组中的最小值和最大值？

Question

How can I easily obtain the min and max values from a very big JavaScript Array (eg 250 thousand numbers)?

I tried to use this method, but it does not work: JavaScript: min & max Array values?

I'm debugging in VisualStudio where I don't get any error, while in the browser I get "Maximum call stack size exceeded".

Example code:

var max = Math.max.apply(-Infinity, arr);
var min = Math.min.apply(Infinity, arr);

"arr" is my very big array.

Answer 1

It is working fine for me

var min = Math.min.apply(Math, array);
var max = Math.max.apply(Math, array);

Answer 2

For large arrays of mentioned sizes you can not use Math.min() or Math.max() safely. I believe this is how it should be done.

 var arr = new Array(1000000).fill().map(_=> ~~(Math.random()*10000000)), findMax = a => a.reduce((res,cur) => res < cur ? cur : res ,-Infinity); console.log(findMax(arr));
