What it is

javascript-algorithms is a comprehensive reference implementation repository containing 100+ algorithms and data structures written in JavaScript, each with explanatory READMEs, test suites, and links to further reading. It serves as both an educational resource and a code reference for developers learning algorithmic concepts through concrete, tested examples across cryptography, graph theory, sorting, searching, and dynamic programming domains. Modular flat structure: src/algorithms contains thematic subdirectories (cryptography/, graph/, sorting/, etc.), each with an algorithm subdirectory (e.g., caesar-cipher/) containing the implementation file (caesarCipher.js), dedicated test…

Start here

Read these in order:

• src/algorithms/sorting/Sort.js — Foundation: doesn't import anything internally and is imported by 10 other files. Read first to learn the vocabulary.
• src/algorithms/graph/depth-first-search/depthFirstSearch.js — Foundation: imported by 6, no internal dependencies of its own.
• src/algorithms/math/complex-number/ComplexNumber.js — Built on the foundation; imported by 4 downstream files.
• src/algorithms/math/euclidean-distance/euclideanDistance.js — Built on the foundation; imported by 2 downstream files.
• src/algorithms/math/fourier-transform/fastFourierTransform.js — Layer 2 — application-level code that wires the lower layers together.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

No package.json or dependency manifest is visible in the provided data. To set up locally: (1) verify the repository manifest by checking for package.json in the root; (2) clone with `git clone https://github.com/trekhl…

Daily commands:

Commands cannot be precisely determined without seeing package.json. Likely: npm install to install test dependencies, then npm test to run Jest test suites across all algorithms. Verify the actual scripts in packag…

Key cautions & unknowns

• Concentrated ownership — top contributor handles 57% of recent commits
• No obvious hidden traps are evident from the data provided. The repository is a pure algorithm reference with no external service dependencies, configuration files, or environment variables mentioned. However, some…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.

Evidence note

Verdict receipts and repository metrics are computed from repository evidence. Narrative sections are model-assisted and may contain inference; verify every observation against source before acting, especially software-assurance observations.
