How to convert String into Array in javaScript

Question

I have a string like "[1,2,3]" and I want to convert it into array like [1,2,3] using JavaScript. Can anyone help me to do this?

Is your code snippet alright? It looks like nothing shows up when I run it. — Hernán Alarcón

Since the string you want to convert is compatible to the JSON format (JavaScript object notation), you can use JSON.parse to convert it into an array:

const str = "[1,2,3]";
const arr = JSON.parse(str);
console.log(arr);

Here you go

  var dat = "[1,2,3]";

  var myData = JSON.parse(dat);
  console.log(myData);
