Exploring VSCode

Create a new directory to hold your source code, and fire up VSCode. This can be done by navigating to the directory, and executing code . from the command line. On Windows systems, fire up VSCode, and then Select File | Open folder from the menu bar. Hit Ctrl+N to create a new file, and type the following:

console.log("hello vscode"); 

Note that there is no syntax highlighting at this stage, as VSCode does not know what type of file it is working with. Hit Ctrl+S to save the file, and name it hello.ts. Now that VSCode understands that this is a TypeScript file, you will have full Intellisense and syntax highlighting available.
