JavaScript (abbreviated as JS) is a high-level interpreted programming language that adheres to the ECMAScript standard. This language is also described as dynamic, multi-paradigm, and prototype-based.
Here are some intriguing JavaScript facts:
JavaScript, along with HTML and CSS, is one of the three fundamental components of the internet (World Wide Web). It enables interactive web pages and is hence a necessary component of online applications. The majority of websites utilize it, and all major web browsers include a JavaScript engine dedicated to executing it.
JavaScript is a single-threaded language. This is why many people who use multi-threaded programming believe it is sluggish since it does not adequately utilize all of the CPU cores.
Despite several similarities between JavaScript and Java, such as language names, standard libraries, and grammar, these two languages are unique and differ greatly in design.
Arrays and objects, like all other programming languages, may be formed using a simple shorthand syntax. These literals constitute the foundation of the JSON data format.
Regular expressions are supported in JavaScript in a similar way to Perl, which provides a compact and powerful vocabulary for text manipulation that is more advanced than the built-in string methods.
A “JavaScript hijacking” CSRF attack occurs when a tag on an attacker’s site breaks a page on the victim’s site that provides sensitive information such as JavaScript or JSON. (Source: Wikipedia)
All current Web browsers with built-in interpreters support JavaScript.
