Question

Fill in blanks to make the variable arr3 look like the following: [1, 2, 3, 4, 5, 6, 7, 8].

const arr1= [1, 2, 3];
const arr2 = [5, 6, 7, 8];
let arr3 = [...arr1, __, ...arr2];

Answer 1

Arr1 is defined as 1,2,3 and arr2 is defined is 5,6,7,8
It’s supposed to read 1,2,3,4 and so on.
Starting the clause you have to write...and the arr sequence in this case arr1. The next section is easy as it’s just the number 4 because if you look at it 4 is still missing between arr1 and arr2.

arr1
...
4

Answer 3

Answer 4

let a = [1,2];
let b = [3,4];
