From a6582190618a5fafe85addc598d0d927d155a8df Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ciar=C3=A1n=20Eaton?= <86569883+EatonCiaran@users.noreply.github.com> Date: Wed, 21 Jul 2021 19:48:49 +0100 Subject: [PATCH 1/2] Tidying things up. * Fix inconsistent use of single and double quotes. Now favours double quotes. * Fix inconsistent space and tab indenting, and remove trailing whitespace. Now 4 space indent. * Removed unneeded semicolons on function declarations and for loops * Fix some typos, clarify some comments/messages, more consistent casing * Fix invalid HTML (lack of title element) and made it HTML 5. * Rename license file to standard convention * Remove custom equalTo function and instead use deepEqual for better error messages when type mismatch. * Make answer prompts more consistent i.e. some hinted for a string, only 1 really needs that * Flesh out README * Other general Prettier changes e.g. typeof not needing brackets; add trailing commas to objects and arrays; spaces before brackets, after commas, and between operators. --- .gitignore | 3 +- license.txt => LICENSE | 0 README.md | 19 +++- jskoans.htm | 78 +++++++------- support/koans.js | 144 ++++++++++++------------- topics/about_arrays.js | 40 +++---- topics/about_asserts.js | 13 ++- topics/about_assignment.js | 11 +- topics/about_control_structures.js | 91 ++++++++-------- topics/about_equality.js | 22 ++-- topics/about_functions_and_closure.js | 87 +++++++-------- topics/about_numbers.js | 21 ++-- topics/about_objects.js | 31 +++--- topics/about_operators.js | 69 ++++++------ topics/about_prototypal_inheritance.js | 59 +++++----- topics/about_prototype_chain.js | 48 ++++----- topics/about_reflection.js | 50 ++++----- topics/about_regular_expressions.js | 24 ++--- topics/about_scope.js | 18 ++-- topics/about_strings.js | 30 +++--- topics/about_this.js | 67 ++++++------ topics/about_truthyness.js | 17 ++- 22 files changed, 472 insertions(+), 470 deletions(-) rename license.txt => LICENSE (100%) diff --git a/.gitignore b/.gitignore index 986544fb..3333e7a4 100644 --- a/.gitignore +++ b/.gitignore @@ -1,2 +1,3 @@ *.swp -.idea \ No newline at end of file +.idea +.vscode/ \ No newline at end of file diff --git a/license.txt b/LICENSE similarity index 100% rename from license.txt rename to LICENSE diff --git a/README.md b/README.md index 6a5de4ac..cb69fdb9 100644 --- a/README.md +++ b/README.md @@ -1,12 +1,25 @@ -Update +Javascript Koans ====== +## Overview + JavaScript Koans is an interactive learning environment that uses failing tests to introduce students to aspects of JavaScript in a logical sequence. -The inspiration for this project comes from the Edgecase Ruby Koans and the book 'Javascript: The Good Parts'. +The inspiration for this project comes from the [Edgecase Ruby Koans](http://www.rubykoans.com/) and the book '[Javascript: The Good Parts'](https://www.oreilly.com/library/view/javascript-the-good/9780596517748/). + +## Getting Started -Open the file jskoans.htm in your favourite browser and make the tests pass. +Open the file [jskoans.htm](jskoans.htm) in your favourite browser and make the tests pass by editing the files located in the `topics` directory + +## Further Information The koans use the [Qunit](http://qunitjs.com/) test syntax and test runner.
