Description

There is a rule for prop value with function creation (bind, function(...), or arrow function): react/jsx-no-bind But I can't find a rule for array ([]) or object ({}) creation.

It would be useful since it would help to avoid useless renders of pure components.

Contributor guide

Research direction
Implement a new ESLint rule that warns when array or object literals are passed as props in JSX render, similar to react/jsx no bind.
