Javascript program to find the area and perimeter of the triangle

In this video, we will write a Javascript program to find the area & perimeter of triangles.

Area of a Triangle:
The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2- dimensional plane.
Formula:
A = 1/2 × b ×h

The Perimeter of a Triangle:
To calculate the perimeter of a triangle, we just add the length of its all sides. 
Suppose, if a triangle has sides x, y, and z, also the perimeter of that triangle will be:
P = (x+y+z)

Example: 
Input 
h and b : 3 & 4
Output 
Area = 6
Perimeter = 10

Now, in this video, we calculate the area & perimeter of the triangle using 2 different methods:
1. Using simple formula [height and base of the triangle]
2. Using the user to define a function

Apart from that the time and space complexity covered in this video.
