Question 1

How do I run tests for a specific LeetCode problem in this repo?

Accepted Answer

Use the command `node Test.js <problem_file_path>`, such as `node Test.js ./LeetcodeProblemsTests/Algorithms/easy/2Sum_Test.js`. This executes the built-in test function for that solution, allowing you to verify correctness locally.

Question 2

Is Algorithms-Javascript better than other LeetCode solution repositories?

Accepted Answer

It excels for JavaScript-focused learners with integrated testing and linting, but lacks the community discussions and multiple language support of larger repos like LeetCode's official solutions. It's best for hands-on coding practice in JS.

Question 3

Can I contribute my own solutions to Algorithms-Javascript?

Accepted Answer

Yes, contributions are welcome via pull requests. The README specifies that each new problem should include a description, test file with a `test()` function, and an entry in the README list, as shown in the provided PR example.

Question 4

How to use ESLint to fix code style issues in this project?

Accepted Answer

After running `npm install` to install dependencies, use `npx eslint LeetcodeProblems LeetcodeProblemsTests --fix` to automatically correct linting errors. This ensures code consistency across all files, as mentioned in the linter section.

Question 5

Are there SQL solutions for database problems in this repo?

Accepted Answer

Yes, it includes SQL solutions for LeetCode database problems, categorized by difficulty—for example, hard problems like Trips and Users and easy ones like Combine Two Tables, with links to the original questions.

Question 6

What's the best way to prepare for interviews using this repository?

Accepted Answer

Use it as a reference to study JavaScript implementations, run tests to check your solutions, and practice with the utility classes. However, supplement with platforms like LeetCode for timed practice and explanations to fill gaps.
