Error "tsc command not found" when compiling TypeScript

Hello everyone! I just started learning TypeScript and ran into a problem when trying to compile my first file. I installed Node.js and npm, created a simple file `hello.ts`: ```typescript function greet(name: string): string { return `Hello, ${name}!`; } console.log(greet("World")); ``` I'm trying to run compilation via terminal with the command `tsc hello.ts`, but I get the error: "tsc command not found". I checked that Node.js and npm are installed — the commands `node -v` and `npm -v` work. I tried to install TypeScript globally via `npm install -g typescript`, but it still doesn't work after that. What could be the problem? Maybe I need to configure something extra or set up paths? I'm using Windows 10, if that matters. I would be grateful for help to a beginner! <<>>
