      1. <div {...foobar} />

    • Refs

    • Mutable Properties

      If you are using a particular library (like react-intl) that uses object properties, and you are sure that the element won’t modify its own props, you can permit objects to be allowed for specific elements.

      This will skip the Mutable Properties deopt.

      1. {
      3.     [
      4.       "@babel/plugin-transform-react-constant-elements",
      5.       { "allowMutablePropsOnTags": ["FormattedMessage"] }
      6.     ]
      7.   ]
      8. }
