I got an error while configuring TypeScript Program.
tsc: The term 'tsc' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Typescript might not be installed globally for a reason, so do so.
npm install -g typescript // install globally
If you want to convert .ts files into .js, do this as per your need
tsc path/file.ts // file.ts will be converted to file.js
tsc // all .ts files will be converted to .js files with in the directory
tsc --watch // converts all .ts files to .js, and watch changes in .ts files
