In JavaScript, the Proxy object enables you to intercept and customize the behavior of fundamental operations on objects, such as property lookup, assignment, enumeration, function invocation, and more. With Proxy, you can control the behavior of objects in ways that…
In modern JavaScript, async/await provides a cleaner and more readable way to work with asynchronous code compared to traditional callback functions or .then() chains with Promises. Introduced in ES2017, async and await allow you to write asynchronous code in a…
JavaScript modules allow you to split your code into separate files, each encapsulating specific functionality. Modules help in organizing, maintaining, and reusing code by exporting and importing functions, objects, or values from one file to another. JavaScript modules are supported…
Typed arrays in JavaScript provide a way to work with binary data using arrays of fixed types and sizes. They are particularly useful when interacting with raw binary data from external sources such as files, network operations, or when performing…
A WeakSet in JavaScript is a special type of set that allows you to store weakly held objects. Like a regular Set, a WeakSet stores a collection of unique values. However, WeakSet differs from Set in several important ways: Only…
A WeakMap in JavaScript is a collection of key-value pairs where keys are objects and values can be any data type. Unlike a regular Map, the keys in a WeakMap are weakly referenced, meaning they do not prevent garbage collection…
Bitwise operations in JavaScript operate directly on the binary representations of numbers. These operations are performed at the bit level, which makes them useful for tasks like low-level programming, working with binary data, manipulating flags, or performing calculations in certain…
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy to read and write for humans and machines. A JSON object literal is a way to represent structured data as key-value pairs using JSON syntax. JSON object literals…
The JSON.parse() method in JavaScript is used to convert a JSON string into a JavaScript object. This method is particularly useful for transforming data received from APIs or local storage into a format that can be easily manipulated in JavaScript.…
The JSON.stringify() method in JavaScript converts a JavaScript object or value into a JSON string. This is particularly useful when you need to send data to a server in the JSON format, or when you want to store JavaScript objects…
