 ## Computed values
 
-Sometimes we need state that depends on other state - in Vue this is handled with component [computed properties](computed.html#computed-properties). To directly create a computed value, we can use the `computed` method: it takes a getter function and returns an immutable reactive [ref](reactivity-fundamentals.html#creating-standalone-reactive-values-as-refs) object for the returned value from the getter.

 ## `watchEffect`
 
-To apply and _automatically re-apply_ a side effect based on reactive state, we can use the `watchEffect` method. It runs a function immediately while reactively tracking its dependencies and re-runs it whenever the dependencies are changed.
