  • We will explore a ternary operator in Javascript in this tutorial and see how helpful it is for clear code. Every developer or programmer aspires to write clean code since it is a good practice. To shorten the code, use the ternary operator (?:) in JavaScript.

  • A character pattern is what makes up a regular expression. The text uses the pattern to do “search-and-replace” operations that match patterns. Further, a RegExp Object in JavaScript is a pattern with properties and methods.

  • The array’s chosen elements are returned as a new array by the slice() method. The slice() method also chooses between a specified start and a specified (not inclusive) end. However, the original array is unaltered by the slice() technique.

  • A heatmap is used to create a visual depiction of a matrix. It draws a matrix on the graph, with different color hues representing different values. We can utilize the seaborn to generate heatmap plots in the seaborn module.heatmap() function. The default size of the plot may not provide a good picture of the data when depicting a huge matrix.

  • When provided with an array, the forEach() function is responsible for calling a function for every item in the given array. However, it is worth noting that this method does not execute when no elements exist.

  • 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.
