Higher Order Functions are functions that take other functions as arguments or return functions as their results. The idea of Higher Order Functions is borrowed from functional programming, and it allows JavaScript to be more expressive and concise. Higher Order Functions are a powerful tool in the hands of developers, as they can use them … Read More “Javascript | Higher Order Functions with examples” »
JavaScript is a prototype-based language, which means that it uses a mechanism called Prototype Inheritance to create new objects. Prototype Inheritance allows an object to inherit properties and methods from another object, known as its prototype. In this article, we’ll explore the basics of Prototype Inheritance in JavaScript, and provide examples of how to use … Read More “Prototype Inheritance: Understanding the Basics” »
Closures are an important feature of JavaScript that allow functions to access and manipulate variables that are outside of their own scope. A closure is created when a function is defined within another function, and the inner function retains access to the outer function’s variables, even after the outer function has completed execution. To understand … Read More “Mastering Closures in JavaScript” »
Currying is a technique in functional programming where a function that takes multiple arguments is transformed into a series of functions that each take a single argument. This can make it easier to compose functions and create reusable code. In JavaScript, currying can be accomplished using closures and recursion. In this article, we’ll explore how … Read More “Infinite Currying in JavaScript” »
Currying function is a popular technique in functional programming, and it’s an essential concept to master when writing JavaScript code. Currying function is a way to transform a function with multiple arguments into a sequence of functions that each take a single argument. In other words, currying converts a function of N arguments into a … Read More “Currying Function in JavaScript” »
In JavaScript, variables and functions can have either a dynamic scope or a lexical scope. Understanding the difference between these two types of scope is important for writing maintainable and effective code. Additionally, understanding the “this” keyword and its related methods, Call, Bind, and Apply, can help you manipulate function execution and scope. In this … Read More “Understanding Dynamic and Static Scope in JavaScript with Call, Bind, and Apply” »
In JavaScript, functions are a fundamental building block of the language. They allow us to encapsulate a piece of code that we can reuse throughout our application. In this article, we will discuss function invocation and how it relates to function scope and block scope in JavaScript. Function Invocation Function invocation refers to the process … Read More “Function Invocation and Scope in JavaScript” »
Hoisting is a term used in JavaScript to describe the behavior of variable and function declarations being moved to the top of their respective scopes during the execution of the code. This can sometimes lead to unexpected behavior and bugs in your code if you’re not familiar with how it works. In this article, we’ll … Read More “Understanding Hoisting in JavaScript” »
In JavaScript, an execution context is the environment in which a piece of code is executed. It consists of three main components: the Variable Environment, the Lexical Environment, and the This Binding. Understanding how these components work together is key to understanding how JavaScript code is executed. Variable Environment The Variable Environment is where the … Read More “Javascript | execution context & Lexical Environment” »
there are several ways to remove an element from an object. Here are some of the most common methods: The delete keyword can be used to remove a property from an object. Here’s an example: const obj = { a: 1, b: 2, c: 3 }; delete obj.b; console.log(obj); // { a: 1, c: 3 … Read More “Method of removing an element from object” »
