Struggling to set the guide to have 42 parts but blank??

var mixture = ["hello","hellos","hi",2,4, true]; var guides = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];

you can create an array with new Array(). If you pass that constructor a number, it sets the length of the array and creates that many number of empty values:

var guides = new Array(42);
