Generators are a powerful feature introduced in ECMAScript 6 (ES6) that allows you to pause and resume the execution of a function. They provide an elegant and flexible way to work with sequences of data, asynchronous operations, and more. In this article, we will explore generators in JavaScript, their syntax, and various use cases with … Read More “Understanding Generators in JavaScript and their Usage” »
1 Reverse String Write a function that reverses a string. The input string is given as an array of characters s. You must do this by modifying the input array in-place with O(1) extra memory. Example 1: Input: s = [“h”,”e”,”l”,”l”,”o”] Output: [“o”,”l”,”l”,”e”,”h”] Example 2: Input: s = [“H”,”a”,”n”,”n”,”a”,”h”] Output: [“h”,”a”,”n”,”n”,”a”,”H”] Constraints: Solution: 2 Longest Common Prefix Write a function … Read More “String related LC questions | Javascript” »
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” »
JavaScript is known for its flexibility, which is partly due to its dynamic typing system. Unlike some other languages, JavaScript does not require you to declare the data type of a variable before using it. Instead, the type of a variable is determined at runtime based on the value assigned to it. This means that … Read More “Understanding Data Types 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” »
decorator is a design pattern that allows you to modify the behavior of an object or function without directly modifying its source code. It involves wrapping a function or object with another function that can modify its behavior or add new functionality. There are different ways to create a decorator in JavaScript, but one of … Read More “Understanding Decorators in JavaScript with example code” »
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” »
