In this article, we will write a C++ program that implements a Max Heap. A Max Heap is a binary tree where the value of each node is greater than or equal to the values of its children. We will explain how to create a Max Heap using arrays and implement operations like insertion and deletion. The article will cover the following topics: What is a Heap? What is Max Heap? What is Heapify? Max Heap Implementation Deletion from ... Read More
Separating objects based on properties in JavaScript means rearranging a group of objects into a new structure where objects that share the same value for a specific property are placed together. Objects are collections of key-value pairs. It stores large data as a key with associated information as its value. In JavaScript, you often need to group objects inside a larger object based on certain properties. Separating objects based on properties in JavaScript can be done by writing a simple function using the reduce method. In this article, we will understand how to do this effectively. Understanding the Problem ... Read More
Extracting values between various square brackets can be done using JavaScript regular expressions. The regular expressions in JavaScript are useful for extracting values enclosed within different types of brackets, such as square brackets ([ ]), curly brackets ({ }), and parentheses "( )". In this article, we'll look at how to use JavaScript's RegExp to find and get content that is inside square brackets easily. Understanding JavaScript RegExp Regular expressions (RegExp) are patterns used to match and manipulate strings in JavaScript. JavaScript RegExp helps you find and get text that is inside specific brackets by using patterns. The ... Read More
Checking whether a number is NaN (Not a Number) or finite is important while working with numerical computations in JavaScript. NaN (Not a Number) indicates a value that can't be represented as a number, often occurring from invalid operations like dividing zero by zero (0/0). Finite numbers are all real numbers in JavaScript that are neither Infinity, -Infinity, nor NaN. JavaScript provides several built-in methods to determine if a value is NaN (Not a Number) or if a number is finite. In this article, you will understand how to check if a number is NaN or finite using these built-in ... Read More
In JavaScript, the Object.getPrototypeOf() method is used to get the prototype of a specified object. This method is used to check prototype of user created object and is often used to compare if the two given objects have the same prototype or not. This method is important for JavaScript's prototype-based inheritance, helping developers understand and work with the prototype chain of objects. In this article, we will look at into the syntax, usage, and examples of getPrototypeOf(). Syntax of the Object.getPrototypeOf() Function The basic syntax for Object.getPrototypeOf() is as follows: Object.getPrototypeOf(obj) obj(parameter): The object whose prototype is to be ... Read More
The onclick event is a useful feature for calling a function in JavaScript. The onclick event allows you to execute a function when a user interacts with an element, such as clicking a button. This article will guide you on how to use the onclick event to call a JavaScript function. What is Onclick Event? The onclick event is triggered when a user clicks on an HTML element. It is commonly used to execute a JavaScript function or a block of code in response to a mouse click on an HTML element, such as a button, link, or any ... Read More
Extracting unique values from an array means finding and getting only the different elements from a given array, eliminating duplicates. An array is a data structure that stores the same type of data in a linear form. Sometimes it contains duplicate items also. To extract unique values from an array in JavaScript, you can do it by using the set object, the filter() method, the reduce() method, and the includes() method. In this article, we will filter out unique values and return an array containing unique elements. Extract Unique Values from an Array Extracting unique values from an array ... Read More
Searching strings for specific patterns is a common task in JavaScript. Strings are data types and are represented as a sequence of characters. Searching patterns means verifying the presence of a specific pattern in a given string. A pattern would be a specific word, specific characters, and so on. JavaScript offers several powerful methods for pattern matching, such as inbuilt string methods and regular expressions. This article will guide you on how to search strings for specific patterns in JavaScript. Table of contents Searching strings for specific patterns in JavaScript can be done in the following ways: ... Read More
Replacing object keys with an array is a common task every developer does while working with data transformations. An object is a data structure that stores data in the form of key-value pairs, and an array stores values of the same data type in a linear form. Sometimes, developers need to use object keys with an array. This article explains how to efficiently replace object keys using arrays in JavaScript. We are required to write a JavaScript function that takes in an object and an array of literals. The length of the array and the number of keys in the ... Read More
