Hello world in JavaScript

1. Overview

JavaScript algorithms for beginners can be a great way to learn the basics of coding and data structures. JavaScript is a powerful programming language that can add interactivity to a website.

In this JavaScript basics for beginners tutorial, you will learn about some fundamentals of JavaScript like Variables, Arrays, Loops, and Functions.

2. JavaScript addition of 2 numbers

JavaScript addition is a fundamental skill that any developer must master. In this example, we take two numbers and store the result in a variable named “sum”.

It creates a variable called x and assigns it the value 5.
It creates a variable called y and assigns it the value 2.
It creates a variable called z and assigns it the value of x + y.
It prints the value of z to the console.

var x = 5;
var y = 2;
var z = x + y;
console.log(z);

//Addition of 2 Sting
var txt1 = "What a very ";
txt1 += "nice day";
console.log(txt1);

//JavaScript Arrays
var cars = ["Saab", "Volvo", "BMW"];
console.log(cars);

//Accessing the First Array Element
fruits = ["Banana", "Orange", "Apple", "Mango"];
var first = fruits[0];
console.log(first);

//Accessing the Last Array Elemen
fruits = ["Banana", "Orange", "Apple", "Mango"];
var last = fruits[fruits.length – 1];
console.log(last);

//Adding Array Elements
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.push("Lemon");
console.log(fruits);

3. Conclusion
