### JavaScript Syntax:

JavaScript Syntax is a set of rules which defines that our JavaScript program has the correct structure or not.

In the program we usually perform the following things:

-   Declaration of variables
-   Assignment of values.
-   Computation of values by using operators

//declaration of variables
const firstNumber = 100;
const secondNumber = 5;
const thirdNumber = firstNumber + secondNumber;
console.log(thirdNumber);

**Note:**

To be an expert JavaScript developer, we should have a clear understanding of values, variables, operators, and their syntaxes.

#### JavaScript values :

A value is the representation of some entity that can be executed by a program.

In JavaScript there are two types of values:

-   Fixed values are known as literals.
-   Variables values are known as variables.

**JavaScript literals:**

JavaScript literals are values that cannot be changed, you do not need any type of keyword to write literals.

**JavaScript literals syntax:**

A JavaScript literal can be a numeric value, string, floating-point value, a boolean value, or even an object. In simple words, any value is literal.

//numerical literal
const firstNumber= 1123;
const secondNumber = 1334;
console.log(firstNumber);
console.log(secondNumber);

// Boolean literal
const isSunny= true;
console.log(isSunny);

//string literal
const greeting = "hello-world";
console.log(greeting);

//array literal
const numberList =[1,2,3,4,5,6];
console.log(numberList);

**Note:**
The complete detail of each literal will be discussed later in the course.

This introductory course for beginners in programming gives you an opportunity to create your own projects very soon. JavaScript is a main language of web applications and web pages, and it's quite easy to understand.

The syntax of the JavaScript programming language is the set of rules that defines how a JavaScript program will be written and interpreted (by both the runtime system and by human readers).

JavaScript is dynamically typed (also called loosely typed) scripting language. That is, in javascript variables can receive different data types over time. Datatypes are basically typed of data that can be used and manipulated in a program.
