How to resize an array?
We can resize an array very simple way. See the following example -
let animals = ["Dog", "Cat", "Goat", "Horses"]
console.log(animals.length) // 4
console.log(animals) // ["Dog", "Cat", "Goat", "Horses"]
Now resize the array using length parameter as bellow
animals.length = 5
Now see what happend
console.log(animals.length) // 5
console.log(animals) // ["Dog", "Cat", "Goat", "Horses", empty]
or
animals.length = 3
console.log(animals.length) // 3
console.log(animals) // ["Dog", "Cat", "Goat"]
now
animals.length = 5
console.log(animals) // ["Dog", "Cat", "Goat", empty × 2]
Very nice and easy.
