server.get('/in/docs', (req, res) => {

Answer 1

Use route parameters using colons:

server.get('/:language/docs', (req, res) => {
  console.log(req.params.language); // gives 'in' if you specify 'in', 'fr' if you specify 'fr', etc
});

You can nest parameters as much as you like, and that will give you an object in the req.params field.
