convert a string to array of arrays

Question

I have a string as a prototype of an array if arrays:

'[ [7,8,9], [12,13,14] ]'

Are there any solutions to convert this to array of arrays?

I have used Array.from() with no luck.

You can use eval (usually not recommended):

let str = '[ [7,8,9], [12,13,14] ]';
let arr = eval(str);
console.log(arr);

let str = '[ [7,8,9], [12,13,14] ]';
let arr = JSON.parse(str);
console.log(arr);

The easiest way is to use eval but you know: eval is evil because it could be harmfull and should normally not be used.

let str = '[ [7,8,9], [12,13,14] ]';

eval('arr='+str+';');
console.log(arr);

You can use JSON.parse() Its parse string to JS object.
