Photo by on Rowan Flickr 3 is an API documentation generator for JavaScript, similar to Javadoc or phpDocumentor. You add documentation comments directly to your source code, right alongside the code itself. JSDoc I use JSDoc more than 4 years and found it extremely good and useful. Documentation is important to have in a project. It helps you to save time for remembering, teaching newcomers, support. The project may have different types of documentation. As an engineer, the important part of the documentation is code documentation and JSDoc solves that problem as well. Simple example From the simple example, you may simply and fast understand what parameter’s types are function takes. You should not look inside the function for that. More often functions, methods are more complicated and it takes time to jump into the function and see what parameter’s types are. Good example Here you may find detailed documentation for a module. Just try to go through and if you do not understand what the module does we may have a call ☎️ _famulus - JavaScript library that provides a useful functional programming helpers.

It won’t replace a TypeScript but after you get used to writing JSDoc you will stop be worrying about types and most important you are not needed to waste time on any configuration part. WebStrom So, here you may see that WebStorm highlights which argument is not fitting assignable type. It helps to avoid bugs with types and most importantly save time. VS Code VS Code allows you to leverage some of TypeScript’s advanced type checking and error reporting functionality in regular JavaScript files. This is a great way to catch common programming mistakes. These type checks also enable some exciting quickfixes for JavaScript, including and . add missing import add missing property For VS Code you should add in each file if you want to have that. //@ts-check _Get the best out of Visual Studio Code for JavaScript development_code.visualstudio.com JavaScript Programming with Visual Studio Code 👏 👍 Thank you for reading.
