Closures are a somewhat abstract concept of the JavaScript language and sneak into the compiler-side of programming. However, understanding how JavaScript interprets functions, nested functions, scopes and lexical environments is imperative to harnessing its full potential.
In this article, we will try to demystify said concepts and provide a
Arrays are one of the most widely used data structures in Computer Science. While dealing with a list of items (array), we are often required to look for a particular value in the list. JavaScript contains a few built-in methods to check whether an array has a specific value,
The main purpose of writing code is so that a computer can interpret it as commands. However, it's also important that the code we write is also easily interpretable by fellow developers.
Have you ever gone back to a project and had difficulty understanding the internal logic? Well that's
Almost every website involves collecting user input through html forms. Whenever we collect user data, we have to validate it. In Computer Science, data validation is the process of checking whether the data entered is sensible and reasonable.
Consider developing a form for email subscriptions. In this case, we
We as software developers often stumble into situations where we need to insert a dose of randomness into our code.
In this article, we will look at how to generate random numbers in JavaScript. We will also touch upon a few built-in methods to deal with random numbers. By
Searching, in the context of Computer Science, is the process of locating a particular element in the given list/array. If we pay close attention, we can find search algorithms everywhere.
Consider the process of logging into a website. Entered email and password are searched against the existing key-value
Searching is one of the most commonly performed tasks in the domain of Computer Science. Many algorithms and data structures exist to make searching more efficient.
In this article, we'll look at the idea behind Binary Search and how to implement it in JavaScript.
Binary Search is a very
Sorting refers to arranging items of a list in a specific order (numerical or alphabetic). Sorting is generally used in tandem with searching.
It is generally easier to search for an element (called the key) in a given list if the list is sorted, both visually and algorithmically.
