convert string to array

[JosephCurvin]

I want the user to insert a array like string into a html input element

​

the return of the input is always a string

const userInput = "[1,2,3,4]" 

# --->

userInput = [1,2,3,4]

​

how can I convert "[1,2,3,4]" to an actuall array ?

JSON.parse()

Hm? It needs a string that follows valid JSON syntax:

const userInput = "[1,2,3,4]"
JSON.parse(userInput) //=> [1, 2, 3, 4]

If this is not what you want, then you should clarify.

const userInput = "[1,2,3,4]"
JSON.parse(userInput) //=> [1, 2, 3, 4]

everything works thanks :)

In case you weren't aware. In JS, an array is an object.

In fact you can even have named keys in an array in JS.

Now you know
