find the area of a rhombus in javascript

To find the area of a rhombus in JavaScript, you'll need to know the length of both diagonals. Here's a function that calculates the area of a rhombus given its diagonals:

index.tsx
function rhombusArea(d1, d2) {
  return (d1 * d2) / 2;
}
57 chars
4 lines

To use this function, simply call it with the length of the two diagonals as arguments, like this:

index.tsx
const d1 = 10;
const d2 = 12;
const area = rhombusArea(d1, d2);
console.log(`The area of the rhombus is ${area}`);
115 chars
5 lines

This will output:

index.tsx
The area of the rhombus is 60
30 chars
2 lines

Note that in this function, we are simply multiplying the length of the two diagonals together and dividing by 2. This is because the area of a rhombus is equal to half the product of its diagonals.
