Live Example of Else if and If else Statement in JavaScript

See the Pen by Bikash Panda (@phpcodertech) on CodePen.

In the above example, we create a program to check the language string in if and else if condition.

Where we first define a variable and set the string value. Then we check the language with == double equal operator to check both are equal or not.

If the condition is not satisfied then it goes to else if condition.

As in our example if the statement condition is false and it goes to else if block where it returns true and prints the value on the web page.
