Programming Fundamentals: Loops

Learning Objectives

  • Use loops to iterate over collections of data

Setup

  • Fork this repository and clone your forked version to your machine

  • Install dependencies by running the command below while in the project's root directory:

    npm ci

Instructions

  • Read through the numbered comments in the following files to understand the requirements of this exercise.

    • src/for-loop-basic.js
    • src/for-loop-and-arrays.js
  • Write your code directly below the numbered comment.

  • Add console.log()s to get visibility on your solution and run the file with the command node src/<file>.js etc

  • See src/example.js for some examples

Running tests

  • To verify your solutions, run the test suite by running the npx jasmine command followed by the path to the corresponding test file for each src/*.js file above, eg:

    npx jasmine spec/for-loop-basic.spec.js

  • Alternatively, run:

    npm test

  • To begin with, almost all of the tests will fail - example tests, if they exist, will pass with a green . You'll see a number of red Fs in your console (possibly many), similar to the image below:

  • Your solution is complete when the all the red Fs have been replaced with green .s in your console, as shown below:

Extensions

  • Extension exercises can be found in the src/extensions directory with corresponding tests in the spec/extensions directory.

  • To run the tests for the extensions, you can either run spec files individually as follows:

    npx jasmine spec/extensions/<file>.spec.js

  • Alternatively, run:

    npm run test-extensions
