Without supersets like TypeScript, JavaScript wouldn’t have survived in the cloud-native and microservices era. You can check large-scale code projects more quickly. With use cases like debugging in particular, type-checking speeds up. The extra features do heavy lifting for larger JS projects, primarily by being more specific in code (e.g., explicitly id’ing types of JS variables, hence the name). TypeScript is an evolved, object-oriented superset of JS. Sketching the Nest.js Architecture: JS, TypeScript, Node & Express JavaScript vs. Nest combines a number of developments in the world of JavaScript and positions sees itself filling in the role of providing scalable server-side development (versus frontend). Nest.js calls itself a progressive Node.js framework (note Vue.js also defines itself that way).

But this is where the distinctions become important – understanding the role of a progressive framework like Nest.js and how we got here. But knowing the original or primary intent of a tool like React.js (it’s a library), can make it easier to grasp how it works and with which other JS tools. The differences seem pretty trivial, as a lot of tools seem to work in both limited and expanded capacities. The default tsconfig.There can be confusion out there given the size of the JS ecosystem. Most developers add this file to their root directory. In WebStorm, add a tsconfig.json file by choosing File – New tsconfig.json File from the menu.

The tsconfig.json file is a JSON file that tells the TypeScript compiler how to compile TypeScript to JavaScript. When you’re ready to start writing TypeScript code, add a tsconfig.json file (TypeScript configuration file) to the project. You can use it in any WebStorm project, including built-in project templates using JavaScript frameworks or existing projects. You don’t need to do anything to use TypeScript with WebStorm.

Finally, TypeScript has many syntactical enhancements and features from ECMAScript even before they’re standardized. It also performs module resolution and has the notion of namespaces, so you can more easily organize code. In addition to data types, TypeScript, like JavaScript, is object-oriented, so you can create models that mirror data stores or objects in the real world.

TypeScript offers a full type system, since types are important to create correct code. This might sound easy, and it is – an easy way to get into trouble! This is especially true if some data is accepted from an input source that doesn’t match the expected type. Developers are free to change the data type of variables during a program’s execution. While JavaScript does contain a few primitive types, its type system is loosely typed, and types are inferred by their usage. Types are at the heart of TypeScript, and it performs type checking when compiling to JavaScript. TypeScript is a superset of JavaScript that contains features that make it easier to write and maintain than standard JavaScript. Rachel Appel TypeScript Language Overview
