Dinamyc psuh to array by length

I stuck with my code.

I have an array like this:

let length = 2;
let data1 = ['Label1', 'Label2', 'Label3'];
let data2 = []

I want to push the data2 with data1 value by length. The expectation I want is like this:

data2 = ['Label1', 'Label2', 'Label3', 'Label1', 'Label2', 'Label3'];

anyone can help? thanks

>Solution :

You can easily achieve the result using Array.from and flat

let length = 2;
let data1 = ["Label1", "Label2", "Label3"];
let data2 = [];

data2 = Array.from({ length }, () => data1).flat();
console.log(data2);
