First Javascript Console Application

Summary

A statement in programming is a single instruction that performs a specific operation or action;
In JavaScript, every statement needs to be ended with a semicolon (;);
The console.log statement can be used for displaying some output in the console;
An example of a console.log statement is:


              1
            
console.log("Hello World");
