Nested Loops Lab

In this lab, you will be working with nested loops to solve various problems. Nested loops are a powerful tool in programming, allowing you to iterate over multi-dimensional data structures. Use your understanding of nested loops to complete the tasks.

Getting Started

1. Fork and clone this repository in your command line.

   git clone <url you provide>
   

2. Navigate to the cloned repository's directory on your command line. Then, run the following command:

   npm install
   

   This will install the necessary libraries to run the tests.

3. Open up the repository in your preferred code editor. Follow the instructions below to complete the Lab.

Instructions

Complete each function as described in the index.js file. You will find detailed instructions in the comments and the accompanying tests will guide you on the requirements for each function.

Tests

To run the tests, use the following command in the root directory of your repository:

npm test

This will execute the test suite once.

Continuous Test Watching

If you prefer continuous testing, which reruns tests automatically upon file changes, use this command:

npm run watch

Follow the prompts to exit the continuous test runner.

Running Individual Test Files

Given the variety of tests in this lab, you might want to execute a single test file. You can do this by appending part of the test file's name to the npm test command:

npm test countZeroes

Running Specific Tests

To focus on a specific test, add .only to either a test or describe block in your test file:

test.only("counts zeroes correctly in a 2D array", () => {

This will run only the specified test or all tests within the described block.

NOTE: Remember to remove .only after your test passes to ensure all tests are executed.

Running Files Manually

For manual testing, execute your file with the following command:

node index.js

The output will be displayed in your terminal.
