nodejs specify class type in function code example

Example 1: javascript class

class ClassMates{
	constructor(name,age){
    	this.name=name;
      	this.age=age;
    }
  	displayInfo(){
    	return this.name + "is " + this.age + " years old!";
    }
}

let classmate = new ClassMates("Mike Will",15);
classmate.displayInfo();  // result: Mike Will is 15 years old!

Example 2: parameters types in javascript

/**
 * My function description
 * @param {String} a
 * @param {String} b
 * @param {Number} amount
 * @example
 * // returns "fooBar fooBar"
 * myFunction('foo', 'Bar', 2)
 * @returns {String}
 */
function myFunction(a, b, amount){
  //do stuff
}
//Note that javascript is not a statically typed language and therefore you
//will not recieve any syntax errors for passing in the wrong types.
//The above code works in Visual Studio Code and intellisense.
