/*To check the length of an array, use the length property, just like
with strings. JavaScript array length is NOT fixed, meaning you can
add or remove items dynamically.*/

let emptyArray = [];
console.log(emptyArray.length);
let programmingLanguages = ["JavaScript", "Python", "Java", "C#"];
console.log(programmingLanguages.length);
//0
//4
