-> Note: In advanced scenarios where you need more control over the rendering performance, `mapStateToProps` can also return a function. In this case, that function will be used as the final `mapStateToProps` for a particular component instance. This allows you to do per-instance memoization. See the [Advanced Usage]() section of the docs for more details, as well as [PR #279](https://github.com/reduxjs/react-redux/pull/279) and the tests it adds. Most apps never need this.

 ### Use Selector Functions to Extract and Transform Data
 
-We highly encourage the use of "selector" functions to help encapsulate the process of extracting values from specific locations in the state tree. Memoized selector functions also play a key role in improving application performance (see the following sections in this page and the [Advanced Usage: Performance]() page for more details on why and how to use selectors.)

 ### `mapStateToProps` Functions Should Be Fast
 
@@ -139,7 +139,7 @@ Many common operations result in new object or array references being created:
 - Copying values with `Object.assign`
 - Copying values with the spread operator `{ ...oldState, ...newData }`
 
-Put these operations in [memoized selector functions]() to ensure that they only run if the input values have changed. This will also ensure that if the input values _haven't_ changed, `mapStateToProps` will still return the same result values as before, and `connect` can skip re-rendering.
