javscript clear array code example

Example 1: javascript clear array

let aray = [1,2,3,4,5,6,7,8,9,10];

//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
array = [];

//set the array's length to 0
array.length = 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());

Example 2: javascript array clear

var cars = ["mazda","honda","tesla"];
	cars = []; // clear/empty the array
