Possible disadvantages of JSLint

  • Rigid Rules
    JSLint is known for its inflexibility, imposing rigid rules that might not always align with modern JavaScript practices or individual project requirements.
  • Limited Customization
    There is limited scope for customization in JSLint, which can be frustrating for developers who prefer more control over the rules being enforced.
  • Deprecated Practices
    Some rules enforced by JSLint are considered outdated and may not accommodate modern JavaScript features like newer ECMAScript standards.
  • Learning Curve
    Beginners might find JSLint's strictness and cryptic error messages challenging, leading to a steeper learning curve compared to other linting tools.
  • Negative Developer Experience
    The strictness and sometimes seemingly arbitrary nature of its rules can lead to a frustrating developer experience for those who prefer a more flexible coding style.

    Like many automated code review tools, CodeFactor.io can sometimes generate false positives or negatives, which might require manual inspection.
  • Performance Issues
    Some users have reported performance issues, such as slow analysis times, especially with very large codebases.
  • Learning Curve
    Although the interface is user-friendly, there can be a learning curve associated with interpreting some of the more detailed metrics and reports.
  • Customization Limitations
    The level of customization in the analysis rules and settings can be limited compared to some other code quality tools, potentially restricting its adaptability to specific team needs.

  • Should JavaScript be split into two languages? Google proposal divides opinion
    Absolutely - one for the great minds to play with while running in great circles and one that passes https://jslint.com and is allowed to be on the internet. - Source: Hacker News / 7 months ago
  • JSLint error: Move all 'var' declarations to the top of the function

  • You shall never disrespect the ways of the elders
    Ooh! I'm pretty sure I actually know this one! I watched a bunch of Douglas Crockford talk's at Yahoo! Talking about the weirdness of the language he helped develop (such as this one). He also has built JSLint to help pull out code that runs but can have unexpected results. Booleans in JS evaluate if something is truthy or falsy and undefined is falsy (19:20), however a string of "undefined" would be truthy, and... Source: over 3 years ago
  • Stupid simple problem in JS
    For future, just pop your code into an HTML Validator, a JS Linter, or a CSS Linter and it will check for basic stuff like this. There are also plugins in most IDEs for these kind of things which are incredibly useful. Source: about 4 years ago
