warning

Since JetBrains Rider 2020.2, JSLint support in the IDE has been deprecated.

However, JSLint support is still available through the JSLint plugin, which can be installed on the Settings | Plugins page as described in Installing plugins from JetBrains Marketplace.

Note that JSLint does not fully support some latest ECMAScript features. For more information, refer to JSLint official website.

When JSLint support is enabled, JetBrains Rider highlights errors that JSLint detects, provides descriptions for them, and suggests quick-fixes where possible.

Descriptions of the errors detected in the current file and quick-fixes for them are available from the editor.
