How to split and modify a string in NodeJS

0 votes

I have a string :

var str = "123, 124, 234,252";

I want to parse each item after split and increment 1. So I will have:

var arr = [124, 125, 235, 253 ];

How can I do that in NodeJS?

Hello @kartik,

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

Hope it helps!!

Thank you!!
