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 isn't designed to replace JavaScript. Instead, its purpose is to encourage the proliferation of JavaScript-based platforms by making it easier to write, integrate, manage and maintain code. JavaScript-driven platforms such as NodeJS on the server and ReactJS on client side continue to...
Another major advantage TypeScript provides over JavaScript is a better syntax to scope types. The TypeScript module keyword lets you place type definitions inside a scope and avoid collisions with types from other modules that may use the same name. The contacts sample application isn’t that la...
TypeScript has declaration files to help. First, remember that all JavaScript is valid TypeScript. So if you have something homegrown, you can copy that code right into the designer and the compiler will produce the JavaScript one for one. The better option is to create your own declaration ...
Whenever decorator functions are used, they now have access to a newmetadataproperty on their context object. Themetadataproperty just holds a simple object. Since JavaScript lets us add properties arbitrarily, it can be used as a dictionary that is updated by each decorator. Alternatively, since...
This is a nice quality-of-life improvement to JavaScript, and TypeScript 3.8 implements this syntax. When your module target is earlier thanes2020, TypeScript will output something along the lines of the first code snippet. Special thanks to community memberWenlu Wang (Kingwl)who implemented th...
2012. That means it has been around for about ten years now. This coding language builds on Javascript and gives programmers better tooling at any scale. It had some features that made it useful to programmers, like automatic code completion. This feature is especially useful for front-end dev...
This service enables us to provide you with better tooling, so your JavaScript code can benefit from richer IntelliSense based on type definitions. The new service is lightweight and consumes less memory than the legacy service, providing you with better performance as your code scales. We also...
TypeScript helps you write better JavaScript, tame large JavaScript projects, and prepare for ECMAScript 6 -- and getting started couldn't be easier
TypeScript is a superset of JavaScript that adds static typing to the language, providing better type-checking and code readability. Combining these two technologies creates a robust and scalable development environment, and TypeScript extends JavaScript by adding static typing, classes, interfaces, and...
