find the area of a square in javascript

To find the area of a square in JavaScript, you need to multiply the length of one side by itself. Here's the code for finding the area of a square:

index.tsx
// define the length of the side of the square
let side = 5;

// calculate the area of the square
let area = side * side;

// log the result
console.log("The area of the square is: " + area);

In this code, we define the length of one side of the square as 5. Then we use the formula for calculating the area of a square by multiplying the side length by itself. Finally, we log the result to the console with a helpful message.
