Accessing Methods Inside Classes in OOP in JavaScript

Some methods can be called inside others via this. Let's look at an example. Let's say we have a class with a user and a method that returns a property:

class User {
	show() {
		return this.name;
	}
}

Let's also have a method cape that converts the first letter of a string to capital:

class User {
	show() {
		return this.name;
	}
	
	cape(str) {
		return str[0].toUpperCase() + str.slice(1);
	}
}

Let's use the cape method inside the show method:

class User {
	show() {
		return this.cape(this.name);
	}
	
	cape(str) {
		return str[0].toUpperCase() + str.slice(1);
	}
}

Make a class Student with properties name and surn.

Create a helper method that will get the first character of the string and capitalize it.

Create a method that will return the student's initials, that is, the first letters of his first and last name.
