Problem
We are required to write a JavaScript function that takes in the three sides of a triangle and uses Heron’s formula to calculate its area.
Example
Following is the code −
const s1 = 10; const s2 = 8; const s3 = 7; const findArea = (s1, s2, s3) => { const arr = []; const arguments = [s1, s2, s3]; for(let i = 0; i < arguments.length; i++){ arr.push(arguments[i]); }; let s = (arr[0] + arr[1] + arr[2]) / 2; return Math.sqrt(s * (s - arr[0]) * (s - arr[1]) * (s - arr[2])); }; console.log(findArea(s1, s2, s3));
Output
