How can i separate number and string from an Array collection in JavaScript?

January 4, 2023

I am learning JavaScript, I want to separate number and string from an Array collection. I can’t do this. Can anyone help me how can i do this?

Here is my code example:

const array = [1, 'abc', 3, 'def', 5, 'ghi'];

I want like this:

[1, 3, 5]
['abc', 'def', 'ghi']

How can i do this?

>Solution :

You can do this with JavaScript built-in array.filter() method.

Here is the solution:

const array = [1, 'abc', 3, 'def', 5, 'ghi'];

const numbers = array.filter((item) => typeof item === "number");
const strings = array.filter((item) => typeof item === "string");

console.log(numbers); // [1, 3, 5]
console.log(strings); // ['abc', 'def', 'ghi']

I think it will solve your problem.
