Question 245542 in Javascript Question posted in
A very good W3school tutorial can be found here.

I want to convert the data type string to an Array in javascript like "['123','234]" to ['123','234']

I have a method that gets an array in the form of a string like "['123', '245345','2345']" I want to convert it to an array datatype. Here I want to remove the quotes and want the type to be an array. How can I do it easily in JS?

Input: "['123','234']" // string
output: ['123','234']  //array datatype

    You can try as follows

    const myString = "['123', '234']";


const outputString = myString.replace(/^"(.*)"$/, "[$1]");

console.log(outputString);

    Output:

    [‘123’, ‘234’]

    Like so:

    // Turn it into valid JSON (strings are doublequotes)
const valueFormatted = "['123', '245345','2345']".replaceAll("'", `"`); 
const result= JSON.parse(valueFormatted);
console.log(result); // (3) [123, 245345, 2345]

    You could attempt to use eval()

    let x = eval("['123','234']")

    Will result in your expected output being stored in the local variable x
