  • Arrays are essential for completing programming tasks in any programming language. In fact, arrays refer to list objects with methods for performing mutation operations. The length of a JavaScript array and the types of its items are not fixed. Arrays in JavaScript are used to hold several values in a single variable.

  • In this article, we shall take a look at generating random numbers in JavaScript with practical examples. First, we will explore the definition of Math.random() and use examples to elaborate its applications on our usual daily tasks.

    Strings in JavaScript

    by Lucy

    A sequence of characters is represented and manipulated using the String object. You can use Strings to store data that can be represented as text. Checking the length of a string, building and concatenating it with the plus and += string operators, checking for substrings’ existence or location with the indexOf() method, and extracting substrings with the substring() method are some of the most common operations on strings.

  • New programmers and non-technical people have long mistaken Java and JavaScript, yet the only thing they have in common is the word “Java.” Each is a functional programming language in its own right, with advantages over the other. However, programmers utilize Java and JavaScript for various jobs; thus, one isn’t inherently better.

  • The filter() method returns a new array containing elements that pass a function’s test. The filter() method does not run the function for empty elements. The original array is unaffected by the filter() technique.

  • These algorithms are what we call intermediate sorting algorithms. The main reason for using these algorithms is the lack of scalability in algorithms such as bubble sort. Understanding the limitations of the latter algorithms is critical. For instance, sorting an array of 100000 elements using bubble sort will take a lot of time to complete. Because of this, we need a quick way to sort massive arrays faster.

  • The Algorithm was developed by Edsger Dijkstra, a Dutch programmer, physicist, essayist, and generally an all-around smarty-pants. By a substantial dimension, he helped advance the field of computer science from an “art” to an academic discipline. In fact, most of his discoveries and algorithms are still commonly used today.

  • Loops can run a block of code several times. As a result, loops come in handy if you want to run the same code multiple times, each time with a different value. In addition, the iteration usually runs a fixed number of times.

    Map in JavaScript

    by Humphrey

    You may occasionally need to take an array and process its elements, resulting in a new array with updated elements. Instead of manually iterating over the array with a loop, you can use the built-in Array.map() method.

  • Strings are frequently used in everyday programming. Fortunately, JavaScript has many built-in methods that assist us when working with arrays, strings, and other data types. These methods can be used for various tasks such as searching, replacing, concatenating strings, etc.

  • Forms are one of the most important elements of HTML. Almost every website uses a form in one way or another. Some uses of HTML forms are contact page form, files uploader form, user registration form, etc. If you want to learn more about the basics of creating an HTML form, you can refer to our beginner step-by-step guide on creating forms.

  • CSS is an acronym for Cascaded Style Sheet.  In the modern world, it seems that every business has a functional website. It’s a necessity to make your website professional and also appealing to the human eye. The better your website is, the higher the chances of visitors staying on your website. This is where the power of CSS comes in – styling your web pages.
