You can find the source code organized by chapter under thesrc folder.

Each file has the.js and the.ts extension, so you get both the JavaScript and the Typescript versions of the source code.

Each data structure and algorithm from parts 2 and 3 also have a_test_ folder where you can find the respectiveJest test cases.

Install all dependencies

npm install

Run all tests

npm test

Run a particular example

cd src/01-intronode 01-hello-variables.js

or:

node src/01-intro/01-hello-variables.js

• JavaScript
• TypeScript
• Jest (tests)

Happy Coding!
