Will PureComponents render everytime due to Context?

We've previously learned that instead of using React.Component when creating a class, we can use React PureComponent, which compares the instances to determine if a component should rerender after a state changes.

One of the rules for this to work is to avoid declaring constants in the render method, because otherwise, a different pointer for the constant would be declared, thus the PureComponent changed and ordered to rerender.

Is Context something that won't allow PureComponents to work because of the reasons above? Is there another way to use PureComponents at their best but still keep using Context?

Best regard and thanks for your replies, David
