JavaScript SEO: Best Practices and Debugging Tools
JavaScript is a great option to make website pages more interactive and less boring.
But it’s also a good way to kill a website’s SEO if implemented incorrectly.
Here’s a simple truth: Even the best things in the world need a way to be found.
No matter how great your website is, if Google can’t index it due to JavaScript issues, you’re missing out on traffic opportunities.
JavaScript
JavaScript, often abbreviated as JS, is a programming language that conforms to the ECMAScript specification.
JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic
typing, prototype-based object-orientation, and first-class functions.
Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript enables
interactive web pages and is an essential part of web applications. The vast majority of websites use it for
client-side page behavior, and all major web browsers have a dedicated JavaScript engine to execute it.
As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative programming styles.
It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard
data structures, and the Document Object Model (DOM).
The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics
facilities. In practice, the web browser or other runtime system provides JavaScript APIs for I/O.
JavaScript engines were originally used only in web browsers, but they are now core components of other
runtime systems, such as Node.js and Deno. These systems are used to build servers and are also integrated
into frameworks, such as Electron and Cordova, for creating a variety of applications.
Although there are similarities between JavaScript and Java, including language name, syntax, and respective
standard libraries, the two languages are distinct and differ greatly in design.

Programming language rankings: JavaScript still rules, Python holds off Java
Love it or hate it, JavaScript is the most popular language today, followed by Python and Java,
according to developer analyst RedMonk's Q1 2021 language popularity rankings.
The top 20 in RedMonk's Q1 2021 rankings don't differ much from its July 2020 rankings.
However, RedMonk analyst Stephen O'Grady notes that half of the top 20 "experienced a degree

How to write cleaner code with JavaScript
Destructuring is one of my favorite tools in JavaScript, in simple terms, destructuring allows
you to break down a complex structure (like an array or an object) into simpler parts, though
there’s a bit more to it than that. Let’s see it better in an example...
