ES6 - Template Literals (Template strings)

Watch the video tutorial: ES6 Template Literals (Template strings) #02

In this ES6 JavaScript tutorial we will learn about Template Literals (Template strings).

What are Template Literals?

Template literals are string literals that allows us to embed expressions, multi-line strings and string interpolation.
Template literals are enclosed using backtick ` ` instead of single quotes and double quotes.
Let's print the string Hello World using single and double quotes.
console.log('Hello World');
console.log("Hello World");
Now, let's print the same string using template literal.
console.log(`Hello World`);

ES6 - var let const

Check out the tutorial video: ES6 var let const #01

In this ES6 JavaScript tutorial we will learn to create variables using var, let and const.

The var keyword

Alright, let's begin by creating a variable using the var keyword.
Let's say we want to create a variable x and assign it a value 10. So, we will write the following line.
var x = 10;
Now, if we want to print the value of x we can console log it by writing the following line.
var x = 10;
console.log(x);
And we get the output 10.
Few important points we must note while using the var keyword to declare variables.
We can redefine the same variable x again and we will not get any error.
So, we can write something like the following.
var x = 10;
console.log(x); // 10
var x = 20;
console.log(x); // 20
