JavaScript Array length

The length property provides the size or length of an array.

Example

const fruits = [“Banana”, “Orange”, “Apple”, “Mango”];
let size = fruits.length;

JavaScript Array toString()

The JavaScript method toString() transforms an array into a string containing its array values, separated by commas.

Example

const fruits = [“Banana”, “Orange”, “Apple”, “Mango”];
document.getElementById(“demo”).innerHTML = fruits.toString();

Result:

Banana,Orange,Apple,Mango
