A community-driven style guide for writing consistent, readable, and maintainable JavaScript code.
Idiomatic.js is a community-driven style guide that provides principles and conventions for writing consistent, idiomatic JavaScript. It addresses the problem of inconsistent coding styles across teams by establishing clear rules for formatting, naming, and structuring code to improve readability and maintainability.
JavaScript developers and teams seeking to standardize their codebase, open-source contributors who want to align with community norms, and projects aiming to enforce a unified coding style.
Developers choose Idiomatic.js because it offers a well-established, community-vetted set of guidelines that reduce style debates, make code easier to read and maintain, and help teams collaborate more effectively. Its focus on practicality and consistency over personal preference makes it a trusted resource.
Principles of Writing Consistent, Idiomatic JavaScript
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Backed by over 30 prominent contributors like Rick Waldron and Mathias Bynens, lending credibility and wide adoption in open-source projects.
Covers everything from whitespace and type coercion to naming conventions and practical patterns, with explicit code examples for each guideline.
Emphasizes writing code for maximum clarity and maintainability, as highlighted by quotes from Rebecca Murphey and Idan Gazit in the README.
Includes real snippets for modules, constructors, and function expressions, making it easier to apply guidelines directly in development.
No built-in tooling; teams must separately configure linters like ESLint or JSHint, and rely on code reviews for compliance, which can be time-consuming.
Some recommendations, like avoiding switch statements or using var, may not align with modern ES6+ features or performance optimizations in current engines.
The guide is extensive and prescriptive, which can be daunting for new teams or projects seeking quick, lightweight style adoption.
Guidelines such as 'comma first' prohibition or specific brace spacing might clash with other popular style guides, causing integration friction.
