//example

//as with most coding there are several ways you can do anything
//see whichever works best for your scenario
//set the array to equal a blank array

//set the array's length to 0

//using splice, starts at index 0 & removes everything up to and including that last index
array.splice(0, array.length);
//map or loop through and shift() or pop();
//goes through the array one at a time and removes the last item each time
array.map( () => array.pop());
//goes through the array one at a time and removes the first item each time
array.map( () => array.shift());js delete all array items
