JavaScript Catwalk

Add code to index.js until your exported functions satisfy the instructions below, and pass all the tests (run npm run test to test).

Go through the exercises with your peers. Compare your solutions at the end of each exercise, and talk about why you wrote your solution the way you did. Then, refactor your solution (or write a new function) for the next exercise and repeat the conversation!

Instructions

Exercise 1

Our function, which I have called getWordLengths, takes a string and returns an object. It returns the number of short words (three letters or less), medium words (four or five letters) and long words (six letters or more).

Edit or replace the exampleFunction in index.js, then run npm run test (you don't need to run npm i) to test you solution.

let count = getWordLengths("What a great day for an enormous picnic in my garden!")
/*
  {
  short: 6,
  medium: 2,
  long: 3
  }
 */

Exercise 2

If there are no words in a category, the return object does not include that category.

let count = getWordLengths("Hello") // { medium: 1 }

Exercise 3

Ignore fullstops, exclamation marks, question marks and commas when you count the length of a word.

let count = getWordLengths("Hello!") // { medium: 1 }

About This Activity

These exercises are very short, but they can be implemented in a lot of different ways. The have been designed to include flow operators such as loops and if statements, and to juggle between multiple types of values - your solution might include strings, numbers, objects, arrays and booleans. However, if your solution doesn't include all of these values and operations, that's okay!

What syntax you use for these operations will depend on which version of JavaScript you're used to, or perhaps what frameworks and languages you have learned in the past or use frequently - or even whether you are used to procedural, functional, or object oriented programming!

What informed your solution? Is there a better way to solve this problem?
