jQuery inArray won't find matches

Question

I have an array converted from string using JSON.parse:

 list = "625, 632";    
 list = JSON.parse("["+items_string+"]");

which contains:

 Array [ 625, 632 ]

Trying to find a given item in the array JQuery inArray will always return -1

 if(jQuery.inArray('625', list) > -1){
     //never get here
 }

 console.log(jQuery.inArray('625', list));
 //will print -1

Does anyone knows why?

Documentation says 'The comparison between values is strict'. Maybe searching for a number will yield the expected result. — Alfabravo, Oct 23 '17 at 16:46
console.log(jQuery.inArray(625, list)); try to find int, not string — Aliaga Aliyev, Oct 23 '17 at 16:46
You are comparing a string to a number, that's why you get always `-1`. — Ervin Szilagyi, Oct 23 '17 at 16:47
@Alfabravo I've read that question before, I know inArray is search for the index, and won't output a boolean, still I didn't know what I was missing. — Adry, Oct 23 '17 at 18:59

Pass a number instead of a string

$.inArray(625, [ 625, 632 ]) // `0`

var list = new Array(625, 632);
if( $.inArray(625, list) !== -1 ) {    
    alert("found");
}
