Introduction

Welcome to the Javascript Primer Quiz! This quiz is designed to help with some basics. Your results are not saved, or assessed - this is just a tool to solidify your learning. Remember to review the Handbook's JavaScript Primer info if you get stuck.

How the quiz works

1. The quiz is split up into different thematic sections, with each section having a few code exercises to complete.
2. Each question has a code box where you type your answer. Most are prepopulated with let answer, which is an empty variable container. You need to add your answer (which will be a numeral) by assigning it to the answer variable e.g. let answer = 4.
3. Beneath the code box is a test(s) which starts out red. Once the testing criteria has been met (i.e. the correct answer has been entered), the test will turn green. If you put in an answer and the test(s) stay red, something's not yet right, keep trying!
4. Once all tests for a particular section are green, move on to the next section!

           'answer is correct': (t) => {
             t.isEqual(answer, 2, `${answer === undefined ? "You haven't submitted an answer yet" : "Not quite, try again"}`)
           }
         })
