What is JavaScript?
JavaScript is a high-level, interpreted programming language that is widely used to create interactive web pages. It was created by Brendan Eich in 1995 and has since become an essential tool for web developers2.
Why Learn JavaScript?
JavaScript allows developers to create dynamic content on websites, such as interactive forms, animations, and real-time updates without reloading the page. It is supported by all modern web browsers and can be used for both front-end and back-end development1.
JavaScript Basics
- Syntax : JavaScript syntax is similar to other programming languages like C and Java. It uses curly braces {} to define blocks of code and semicolons ; to end statements.
- Variables : Variables in JavaScript are used to store data and can be declared using var, let, or const.
- Functions : Functions are blocks of code that perform a specific task and can be reused throughout the program.
- Objects : JavaScript is an object-oriented language, and objects are used to represent real-world entities.
JavaScript Features
- Dynamic Typing : JavaScript is a weakly typed language, meaning variables can change types.
- Prototype-based Inheritance : JavaScript uses prototypes for inheritance rather than classes.
- First-class Functions : Functions in JavaScript are first-class objects, meaning they can be passed as arguments to other functions and returned as values.
JavaScript Examples
Here are some basic examples to get you started with JavaScript:
Javascript ✍️
// Changing HTML content
document.getElementById("demo").innerHTML = "Hello JavaScript!";
// Changing HTML attribute values
document.getElementById("myImage").src = "newImage.jpg";
// Changing HTML styles
document.getElementById("myElement").style.color = "blue";
History of JavaScript
JavaScript was originally developed by Brendan Eich in 1995 for Netscape Navigator. It was initially called Mocha, then renamed to LiveScript, and finally to JavaScript1. It has since become a standard for web development and is standardized as ECMAScript.
Conclusion
JavaScript is a powerful and versatile programming language that is essential for modern web development. By learning JavaScript, you can create dynamic and interactive web applications that enhance user experience.
