console.log(`This file has ${lines} lines`);
console.log(`lines.txt has ${linesIn("./lines.txt")}`);
console.log(`This file has ${words} words`);
console.log(`words.txt has ${wordsIn("./words.txt")}`);
will be transpiled to
console.log(`This file has ${7} lines`);
console.log(`lines.txt has ${100}`);
console.log(`This file has ${25} words`);
console.log(`words.txt has ${1000}`);
