Microsoft announced this week the availability of Sonar, an open source linting and website scanning tool designed to help developers identify and fix performance and security issues.
Developed by the Microsoft Edge team, Sonar has been made open source and donated to the JS Foundation. Microsoft will continue making improvements to the project, but external contributions are also welcome.
Linting is the process of analyzing code for potential errors. Sonar looks for a wide range of issues, including related to performance, accessibility, security, Progressive Web Apps (PWA), and interoperability.
