January 2020 (version 1.33.0)

1.33.0 Update

Happy New Year!

We hope you have a great 2020 and will work hard to ensure DeepScan is your handy JavaScript tool.

Please kindly go ahead with the highlights for the latest release.

This version includes a number of updates that we hope you've found some of them helpful.
The key highlights are:

We are enhancing our rules. Check out the newly introduced rules!

MISMATCHED_TYPE_OF_DEFAULT_VALUE - Do not set a default value with an invalid type
REACT_BAD_CONTEXT_TYPE - Do not set an invalid value to the contextType property of a React component

Recognize React-specific objects like React element, context object, context provider and context consumer. This will enable detecting more alarms for REACT_MISMATCHED_TYPE_OF_ARG and REACT_MISMATCHED_TYPE_OF_PROP including invalid plain objects.
Detect REACT_MISMATCHED_TYPE_OF_PROP alarms at the child expressions of a React element when the children prop type is specified

Now we are together with the GitHub Student Developer Pack.

Providing a free trial for qualified GitHub Students, we hope to help students who want to develop and learn JavaScript enjoyably.

Good luck to the future JavaScript developers!

We have added more ESLint plugins which are missing in the analysis.

Remove support for deprecated Firefox-specific APIs: Object.prototype.watch and Object.prototype.unwatch

A false alarm may occur when a computed property is used at object literal
A false alarm may occur when a property value is updated after object literal creation
Leading and trailing whitespaces at JSX text node may not be properly removed
