Full Title or Meme

A superscript of JavaScript that adds strong typing and other aids for good programming practice.

Context

JavaScript was becoming more than just a scripting language in 2019 with object-oriented features like asynchronous calls but without strong typing or other features of monder programming languages. since it seemed unlikely that strong typing would ever be included in javascript, typescript was created to add other features that supported good programming practices.


Examples


Add to ASP.NET project

  1. Add>New Item>TypeScript JSON Configuration File (Do Not change its name)
    1. in tsconfig.json change target library to a current version, like "target": "es2015"
    2. and add this line "outDir": "wwwroot/js" which will force the output from the ts compilation to that dir
  2. Add>New Item> TypeScript File (Any name will work, say add.ts, we assume you are starting with no existing JS, so we call it site.js)
    1. Since we used an existing file, this line is already in the _Layout.cshtml <script src="~/js/site.js" asp-append-version="true"></script>
