-Returns the area of a triangle using only the 3 side lengths, Heron's formula. Assumes that the sides define a valid triangle. Does NOT assume it is a right triangle.
-
-More information on what Heron's formula is and why it works available here: https://en.wikipedia.org/wiki/Heron%27s_formula.
-
-Uses `Math.sqrt()` to find the square root of a value.
-
-```js
-const heronArea = (side_a, side_b, side_c) => {
-    const p = (side_a + side_b + side_c) / 2
-    return Math.sqrt(p * (p-side_a) * (p-side_b) * (p-side_c))
-  };
-```
-
-```js
-heronArea(3, 4, 5); // 6
-```
