I currently have this array: var arr = [] How do I push multiple "hello" strings into the array using a for loop? I tried
var newArray = arr.push("hello")10;
1 Answer
try new Array forEach or simple for-loop should work.
var arr = [];
// method 1
new Array(5).fill(0).forEach(() => arr.push("hello"));
// alternate method
for (let i = 0; i < 5; i++) {
arr.push("world");
}
console.log(arr);
// Updating based on suggesion @mplungjan, quick way without loop.
var arr2 = Array(10).fill("hello");
console.log(arr2)

Oh right, Thanks @mplungjan. Just realising I think further short way is
var arr = Array(10).fill("hello").
var arr = new Array(10).fill("hello")
