Back on the Arrays today - refreshed a few bits of knowledge with the Lunch Picker program in returning a random item from the array using the Math.random function.
let i = Math.floor(Math.random() * a.length);
Also something so simple like returning an array but wanting to separate the array items using a comma and a space caught me out so had to remember to join the array by putting the comma and space in there.
Remember when using the split, reverse & join that you do not need the str in front of it. It can be all done in one:
const newStr = str.split("").reverse().join("");
Its been quite interesting working through the objects section also as there were a few that I had done previously so had seen the changes that were made and still some bits I got stuck on again.
