When we pose the question as “What is TypeScript?” we are getting into a language that builds on JS by incorporating static typing. TypeScript is a statically typed language that is a superset of JavaScript; this means that it has a type system that prevents errors before the JavaScript ...
TypeScript is a language that enables writing better code for large and complex projects. Explore What TypeScript is and its types through this blog.
TypeScript supports definition files that can contain type information of existing JavaScript libraries, much like C++ header files can describe the structure of existing object files. This enables other programs to use the values defined in the files as if they were statically typed TypeScript ...

Going forward, we will continue to work with our partners and the community to evolve TypeScript’s type system to allow users to further express JavaScript in a statically typed fashion. In addition, we will focus on enhancing the TypeScript language service and set of tooling features so tha...
the case for static type-checking has been proven out fairly successfully. Microsoft, Google, and Facebook releasedTypeScript,Closure Compiler, andFlow, respectively. These efforts have been large investments in JavaScript to reap the productivity gains they saw in other statically-typed languages incl...
yeah. And this is the difference between a statically or strongly typed language, where you say, okay, once it has the type it has to be of the type and the type can’t change afterwards. In the weakly or dynamically typed language where the type just depends on where you are in your...
Python adopted a nominative type system in 3.5. You’re still allowed to use duck-typing, but you can also create statically typed functions and variables. And despite duck-typing being close to structural typing, they instead went with nominative typing. There are many reasons for this, and ...

One of the more notable differences is that JavaScript is dynamically typed, which means you do not have to declare types when creating variables. Languages like C, C#, and Java will make you declare variable types. These are called statically typed variables. Languages that use statically typed...
