How to use custom function In Javascript
In this approach, we will define a function that takes the side length as an argument and returns the square of the side length, representing the area of the square.
Syntax:
function functionName(parameter1, parameter2) {
// Function body
}
Example: To demonstrate defining the areaOfSquare function which takes side as parameter which is 5 here and returns the area of square i.e. 25.
Javascript
function areaOfSquare(side) { return side * side;}const sideLength = 5;const area = areaOfSquare(sideLength);console.log(`The area of the square is: ${area}`); |
Output
The area of the square is: 25
