Array.length() can come in handy outside of just getting the length of an array. Sometimes, we want to check if there are any elements in the array. Array.length() can come really handy in those times.
let fruits = []
if(fruits) { console.log("print me") }
// print me
if(fruits.length) { console.log("print me") }
fruits = ["banana", "apple"]
(2) ["banana", "apple"]if(fruits) { console.log("print me") }
// print me
if(fruits.length) { console.log("print me") }
// print me
fruits = []
if(fruits) { console.log("print me") }
// print me
if(fruits.length) { console.log("print me") }
// undefined
