In JavaScript, there are three types of quotes that can be used: single quotes, double quotes, and backticks. While single quotes and double quotes are essentially the same, there is a slight difference when it comes to escaping the quote character within the string. Backticks, on the other hand, were introduced with ES6 in 2015 and have a unique feature - they allow for multiline strings without the need for escape characters....
When working with JavaScript, enforcing the type of a variable at compile time can be challenging because of its dynamic nature. Passing invalid types can lead to runtime errors or unexpected behavior if the types are compatible but not what we expect. However, React offers a solution to this problem through PropTypes. With PropTypes, we can specify the required types for props, and our tools (such as editors and linters) can detect type errors before running the code....
If you’re looking to remove the first character from a string in JavaScript, there is a simple and efficient solution available. By using the slice() method, you can easily achieve this task. Here’s how: const text = 'abcdef'; const editedText = text.slice(1); //'bcdef' The slice() method takes two parameters: the starting index and the ending index. In this case, we pass 1 as the starting index to remove the first character....
JavaScript semicolons are not required but have been a topic of debate among developers. While some prefer using semicolons in their code, others choose to avoid them. Personally, I used to rely on semicolons for years until the fall of 2017, when I decided to experiment with omitting them. I configured Prettier, an automated code formatter, to remove semicolons from my code unless they were necessary for specific language constructs....
To use or not to use? To learn or not to learn? Let’s examine whether you should avoid jQuery altogether and explore the reasons why you should continue using it. jQuery has played a significant role in the JavaScript ecosystem, although its popularity has declined in recent years due to the emergence of modern browsers. However, many people still rely on this JavaScript library. In the early-mid 2000s, when JavaScript applications were not yet prevalent, jQuery became popular as it provided a solution to the limitations of JavaScript at the time....
Introduction This blog post will guide you through the new JavaScript public class fields, providing a simple tutorial on how to use them.

Let’s dive in and explore how to use this feature effectively....
Learn how to sort an array of items by date value in JavaScript.

Styled Components have emerged as a popular solution for incorporating CSS into modern JavaScript. They serve as a successor to CSS Modules, enabling developers to write CSS that is scoped to a specific component without leaking styles to other elements on the page. A Brief History In the early days of the web, CSS didn’t exist, and layouts were created using tables and frames. Eventually, frameworks like Bootstrap and Foundation emerged to simplify grid and layout creation....
