Tuples in TypeScript are a special type of array that allow you to define the number and types of elements that an array can contain. Unlike regular arrays, where all elements must be of the same type, tuples can have…
In TypeScript, arrays are used to store multiple values of the same type. TypeScript adds a level of safety to working with arrays by allowing you to specify the type of the elements in the array. This ensures that you…
In addition to the simple types such as string, number, and boolean, TypeScript includes several special types that are designed to handle more complex or specific scenarios. These special types provide extra flexibility when dealing with type checking, error handling,…
TypeScript is a statically-typed superset of JavaScript that introduces type annotations and compile-time type checking. One of its main features is type safety, which helps prevent errors by catching issues early during development. TypeScript includes a range of simple types…
The console module in Node.js provides a simple way to output information to the terminal or log files. It is similar to the console object found in web browsers but includes several additional features that make it useful in a…
The Buffer class in Node.js is used to work with binary data directly. It allows you to handle raw data such as file contents, network packets, and more, making it a key component for dealing with low-level data operations. Buffers…
The assert module in Node.js is used for writing tests and performing assertions. An assertion is a way to check that something is as expected. If the condition being tested by the assert module fails, it throws an error. This…
In JavaScript, Reflect is a built-in object that provides methods for interceptable JavaScript operations. These methods correspond to the default operations that can be intercepted by Proxy objects. The Reflect object allows us to perform many low-level object manipulations like…
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…
