JavaScript - Syntax

JavaScript is a programming language that is commonly used to add interactivity and other dynamic features to websites. Some basic syntax for JavaScript includes:

Variables: Variables are used to store data and are declared using the keyword "var", "let" or "const". For example: var x = 5;

Data Types: JavaScript has several data types, including numbers, strings, and booleans. Numbers can be integers or floating-point values, and strings are sequences of characters. For example: let name = "John";

Functions: Functions are blocks of code that can be reused. They are declared using the keyword "function", followed by the function name, a list of parameters, and the code to be executed. For example:

function greeting(name) {
console.log("Hello, " + name);

Conditional Statements: Conditional statements are used to make decisions in code. The most basic form of a conditional statement is the if-else statement. For example:

if (x > 5) {

  console.log("x is greater than 5");

} else {

  console.log("x is less than or equal to 5");


Loops: Loops are used to repeat a block of code. The most basic form of a loop is the for loop. For example:

for (let i = 0; i < 5; i++) {



These are just a few examples of the basic syntax of JavaScript. There are many more elements and concepts in the language, such as objects, arrays, and methods that are commonly used in web development.
