# Disallow JSX prop spreading the same identifier multiple times (`react/jsx-props-no-spread-multi`)

<!-- end auto-generated rule header -->

Enforces that any unique expression is only spread once.
Generally spreading the same expression twice is an indicator of a mistake since any attribute between the spreads may be overridden when the intent was not to.
Even when that is not the case this will lead to unnecessary computations being performed.
