# JavaScript Cheatsheet JavaScript is a high-level programming language used primarily for developing web applications. Here is an overview of its features, code blocks, and resources. ## Features - JavaScript is a scripting language that can be used to add interactivity to web pages. - It can be used for both front-end and back-end development. - JavaScript is dynamically typed, which means that variables do not need to be declared before use. - JavaScript supports functional programming paradigms as well as object-oriented programming. ## Code Blocks ### Variables Variables are used to store data that can be used later in the program. ```javascript let variableName = value; ``` ### Functions Functions are code blocks that perform a specific task. They can be called by other parts of the program. ```javascript function functionName(parameter1, parameter2) { // code to be executed } ``` ### Conditionals Conditionals allow the program to make decisions based on certain conditions. ```javascript if (condition) { // code to be executed if condition is true } else if (otherCondition) { // code to be executed if otherCondition is true } else { // code to be executed if neither condition is true } ``` ### Loops Loops allow the program to repeat a set of instructions. ```javascript for (let i = 0; i < 10; i++) { // code to be executed } ``` ### Objects Objects are a fundamental part of JavaScript and are used to store and manipulate data. ```javascript const objectName = { property1: value1, property2: value2, method: function() { // code to be executed } }; ``` ## Resources Here are some resources for learning and using JavaScript: - [JavaScript Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript) - [JavaScript subreddit](https://www.reddit.com/r/javascript/) - [W3Schools JavaScript Tutorial](https://www.w3schools.com/js/) - [JavaScript on Stack Overflow](https://stackoverflow.com/questions/tagged/javascript)
