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

The area in which the AI software agent functions is known as the episodic and sequential environment. The structure of an agent's experiences and the degree to which they impact subsequent behavior and actions vary among these environments. A strong basis for creating AI systems suited to various activities and resolving a range of issues is provided by an understanding of the characteristics and differences of these environments.What is Episodic Environment in Artificial Intelligence?AI agents that work in episodic environments are engaged in tasks that can be characterized as the agent's entire experience divided into multiple independent, self-contained episodes or trials. ...

In this article, we will learn to count triplets with a sum smaller than a given value in JavaScript. Triplets in an array whose sum is less than a provided number is a popular problem in competitive coding and algorithm design. Problem Statement Given an array of integers and a target sum, we need to find the number of triplets (a, b, c). For exampleInput const arr = [5, 1, 3, 4, 7]; const sum = 12;Output 4 Explanation: The valid triplets are :(1, 3, 5)(1, 3, 4)(1, 4, 5)(1, 3, 7), all having a sum of less than 12. ... Read More
In this article, we will learn to check if all the elements are the same in an array in JavaScript. Finding all elements of an array to be the same is a frequent problem in JavaScript, usually needed for data validation, game logic, and algorithm building. Problem Statement We are required to write a JavaScript function that takes in an array of literals. The function should find whether or not all the values in the array are the same. If they are the same, the function should return true, or false otherwise. For Example Input const arr2 = [1, 1, ... Read More
