Courses Plus Student 2,752 PointsThere are a couple of ways you can go about doing this depending on the position of the item in the array you want to remove and insert into another array.
if you want to remove the first item, you can use .shift() to remove and then .push() to insert to the end of another array.
e.g
var a = [1, 2, 3];
var b =[]; // empty array where you want to insert the first item in a(1)
var c = a.shift(); // c holds the value(1) returned by .shift()
b.push(c)
console.log(b); // => [1]
console.log(a); // => [2, 3]
if you want to remove the last item, you can use .pop() to remove and then .push() to insert to the end of another array.
e.g
var a = [1, 2, 3];
var b =[]; // empty array where you want to insert the last item in a(3)
var c = a.pop(); // c holds the value(3) returned by .pop()
b.push(c)
console.log(b); // => [3]
console.log(a); // => [1, 2]
Alternatively, you can use .slice() which allows you to choose a start and end position
