A comment is a piece of text within a program that is not executed. It can be used to provide additional information to aid in understanding the code.
// Prints 5 to the consoleconsole.log(5);
A single-line comment can also be used to comment after a line of code:
console.log(5); // Prints 5
Multi-line comments are created by surrounding the lines with
/* at the beginning and
*/ at the end. Comments are good ways for a variety of reasons like explaining a code block or indicating some hints, etc.
/*The below configuration must bechanged before deployment.*/let baseUrl = 'localhost/taxwebapp/country';

console.log(/* IGNORED! */ 5); // Still prints 5
