How to convert string to array?

Question

I want to convert a string separated by commas and spaces into Number array in JavaScript..
Ex: "2, 44, -7, 8" -> [ 2, 44, -7, 8 ]
And whenever I convert string to array it shows output : [2, 4, 4, NaN, 8]

Answer 1

var arr = "2, 44, -7, 8".split(/\s*,\s*/).map(s => Number(s));

Answer 2

I used split() with a regex matching any number of spaces + comma + any number of spaces to act as separator...

this return a list of numbers stored as string.

then I map that list to another one to convert the strings to numbers ;)

Answer 3
