TypeScript compiler.

# To compile a TypeScript file 'foobar.ts' into a JavaScript file 'foobar.js':
tsc <foobar.ts>

# To compile a TypeScript file into JavaScript using a specific target syntax (default is 'ES3'):
tsc --target <ES5|ES2015|ES2016|ES2017|ES2018|ESNEXT> <foobar.ts>

# To compile a TypeScript file into a JavaScript file with a custom name:
tsc --outFile <output.js> <input.ts>

# To compile all '.ts' files of a TypeScript project defined in a 'tsconfig.json' file:
tsc --build <tsconfig.json>

# To run the compiler using command line options and arguments fetched from a text file:
tsc @<args.txt>

# To type-check multiple JavaScript files, and output only the errors:
tsc --allowJs --checkJs --noEmit <src/**/*.js>
