Convert integer array to string array in JavaScript

I have an array like below:

var sphValues = [1, 2, 3, 4, 5];

then I need to convert above array like as below one:

var sphValues = ['1', '2', '3', '4', '5'];

How can I convert? I used this for auto-complete.

You can use map and pass the String constructor as a function, which will turn each number into a string:

sphValues.map(String) //=> ['1','2','3','4','5']

This will not mutate sphValues. It will return a new array.

Use Array.map:

var arr = [1,2,3,4,5];
var strArr = arr.map(function(e){return e.toString()});
console.log(strArr); //["1", "2", "3", "4", "5"]

Edit:
Better to use arr.map(String); as @elclanrs mentioned in the comments.

just by using array methods

var sphValues = [1,2,3,4,5];   // [1,2,3,4,5] 
sphValues.join().split(',')    // ["1", "2", "3", "4", "5"]

for(var i = 0; i < sphValues.length; i += 1){
    sphValues[i] = '' + sphValues[i];
}

Use .map() at this context that is a better move, as well as you can do like the below code this would add more readability to your code,

sphValues.map(convertAsString);

function convertAsString(val) {
  return val.toString();
}
