The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

ECMAScript Confidence: 95% Arrow up

ECMAScript (or ES).

is a trademarked scripting-language specification standardized by the European Computer Manufacturers Association in ECMA-262 and ISO/IEC 16262.

It was created to standardize JavaScript, so as to foster multiple independent implementations.

JavaScript has remained the best-known implementation of ECMAScript since the standard was first published, with other well-known other implementations including JScript and ActionScript.

Coders commonly use ECMAScript for client-side scripting on the World Wide Web, and it is increasingly being used for writing server applications and services using Node.js.

Type system Confidence: 93% Arrow up

In programming languages, a type system is a set of rules that assign a property called type to various constructs a computer program consists of, such as variables, expressions, functions or modules.

The main purpose of a type system is to reduce possibilities for bugs in computer programs by defining interfaces between different parts of a computer program, and then checking that the parts have been connected in a consistent way.

This checking can happen statically (at compile time), dynamically (at run time), or as a combination of static and dynamic checking.

Type systems have other purposes as well, such as enabling certain compiler optimizations, allowing for multiple dispatch, providing a form of documentation, etc.

JavaScript Confidence: 93% Arrow up

JavaScript is a high-level, dynamic, untyped, and interpreted programming language.

It has been standardized in the ECMAScript language specification.

Alongside HTML and CSS, JavaScript is one of the three core technologies of World Wide Web content production; the majority of websites employ it, and all modern Web browsers support it without the need for plug-ins.

JavaScript is prototype-based with first-class functions, making it a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.

It has an API for working with text, arrays, dates and regular expressions, but does not include any I/O, such as networking, storage, or graphics facilities, relying for these upon the host environment in which it is embedded.

TypeScript Confidence: 79% Arrow up

TypeScript is a free and open-source programming language developed and maintained by Microsoft.

It is a strict superset of JavaScript, and adds optional static typing and class-based object-oriented programming to the language.

Anders Hejlsberg, lead architect of C# and creator of Delphi and Turbo Pascal, has worked on the development of TypeScript.

TypeScript may be used to develop JavaScript applications for client-side or server-side (Node.js) execution.

Scalability Confidence: 72% Arrow up

Scalability is the capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged in order to accommodate that growth.

For example, it can refer to the capability of a system to increase its total output under an increased load when resources (typically hardware) are added.

An analogous meaning is implied when the word is used in an economic context, where scalability of a company implies that the underlying business model offers the potential for economic growth within the company.
