Properties via constructor parameters in OOP in JavaScript

Variables passed through constructor parameters can be written to the object's properties:

class User {
	constructor(name, surn) {
		this.name = name;
		this.surn = surn;
	}
}

Thus, the passed values will become available in all methods of the class. For example, let's use the passed values in some method:

class User {
	constructor(name, surn) {
		this.name = name;
		this.surn = surn;
	}
	
	show() {
		return this.name + ' ' + this.surn;
	}
}

Let's check how it works. Let's create a new object, passing the user's first and last name as a parameter:

let user = new User('john', 'smit');

Let us now turn to our method:

console.log(user.show());

Pass the employee's name and salary to the Employee class constructor and write them to the corresponding properties.

Create a method that will output the employee's name.

Create a method that will output the employee's salary.

Create a method that will increase the employee's salary by 10%.
