A minimalist random generator library for JavaScript that produces random numbers, strings, names, addresses, and more.
Chance is a JavaScript library that generates random data such as numbers, strings, names, addresses, and dice rolls. It solves the problem of creating realistic mock data for testing, simulations, and prototyping by providing a simple, consistent API built on a reliable pseudorandom number generator.
JavaScript developers who need to generate random data for testing, demos, simulations, or any application requiring randomized content.
Developers choose Chance for its minimalist API, comprehensive data generation capabilities, and repeatable randomness via seeding, which is essential for reliable testing and debugging workflows.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Built on a robust pseudorandom number generator, ensuring statistically sound and repeatable randomness, which is essential for reliable testing and simulations as highlighted in the README.
Supports a wide range of data types including numbers, strings, names, addresses, and dice, reducing the need for multiple libraries and simplifying mock data creation.
Allows setting seeds to produce identical random sequences, crucial for debugging and maintaining consistent test results across runs.
Offers a simple, consistent interface while powering a rich ecosystem of dependent tools like CLI utilities and JSON schema populators, extending its utility beyond basic generation.
Relies on Mersenne Twister, which is pseudorandom and not suitable for security-sensitive applications such as token generation or encryption, limiting its use in those contexts.
Focuses on individual data types; generating nested or interrelated data with dependencies requires additional custom logic or integration with external tools.
While it includes some international data, support for non-English languages and region-specific formats may be incomplete, necessitating manual adjustments for global applications.
