js-exercises

Some simple JS exercises for beginners to start with.

The exercises are located in the js-exercises/exercises folder and they look like this:

/**
 * Greets the world with your first steps!
 * @return {str}
 */
function hello() {
  let output = null;
  // put your code between here


  // and here
  console.log(output);
  return output;
}

// exporting to be able to test it
module.exports = hello;

Rules

• Put your solution in the stated place between the comments
• Don't modify the rest of the code ❌
• Enjoy the process 😊

Testing

Once you have written your solution and you want to check if everything is correct, in the terminal use:

make

to run all exercises tests or

make lesson0

to run only the dedicated tests. In this case the ones only for the lesson0.js file.

You should be seeing something like

$ make lesson0
Testing ./exercises/lesson0.js file:
null
  1: Testing that it returns Hello World! => Fail: got null and was expecting Hello World!
