find the area of a triangle in javascript

To find the area of a triangle in JavaScript, we can use the following formula:

index.tsx
Area = (base * height) / 2

2 lines

where base is the length of the base of the triangle and height is the height of the triangle.

Here's the JavaScript code to calculate the area of a triangle:

index.tsx
function triangleArea(base, height) {
  var area = (base * height) / 2;
  return area;
}

// Example usage:
var base = 5;
var height = 10;
var area = triangleArea(base, height);
console.log('The area of the triangle is: ' + area);
231 chars
11 lines

In this example, we define a function triangleArea that takes two parameters, base and height, and returns the calculated area of the triangle. We then call the function with a specific base and height value, and log the result to the console.
