find the area of a rectangle in javascript

To find the area of a rectangle in JavaScript, you can use the following formula:


index.tsx
Area = length * width
22 chars
2 lines

You can write a function that takes length and width as arguments and returns the area:


index.tsx
function calculateRectangleArea(length, width) {
  const area = length * width;
  return area;
}

5 lines

You can then call this function with different values to get the area of different rectangles:


index.tsx
const area1 = calculateRectangleArea(5, 10); // returns 50
const area2 = calculateRectangleArea(7, 3); // returns 21
