Then you can gradually start introducing type annotations into your old JavaScript files, one at a time now (because you're a cautious developer, right?). You can also start using other TypeScript goodies like exporting functions directly instead of having to add a new property on theexportsob...
Within build, create a new file called index.ts. Now you can start writing typescript. I have created a very basic example for index.ts: let i:number = 1; let j:number = 2; let z:number = 3; Now, when we want to compile our typescript, we just have to run the following ...
I’ve taken a quick pass through TypeScript, and while it’s definitely not an exhaustive treatment, it’ll get you going once you pick up AngularJS 2 and start hacking on that. Note that some of the features described here will require particular compiler switches...

That's all we need for our Typescript configuration. Now let's create apnpm-workspace.yamlfile at the root of our project that will tellpnpmwhat packages we will have inside our monorepo. pnpm-workspace makes it surprisingly easier to add and manage multiple packages in a project. ...
TypeScript will also look at this code and, when inside theifclause, will have narrowed the type of thebarproperty tonumber. TypeScript will also let you “get away” with a truthiness check, like this: TypeScript functionaddOne(foo:Foo):number{if(foo.bar){returnfoo.bar+1;}thrownewErro...
