Vue Computed Properties

This lesson is part of Vue · All levels

Summary

Computed property is a derivative value calculated from other reactive data and cached by Vue until its dependence changes. This approach is more efficient than the method for values often used in templates because the results are not recalculated without data changes. Computed can also be made writable with pairs of get and set for specific cases.

The computed results are cached and recalculated only when the dependencies change.
Computed is more efficient than the method for frequently accessed derivative values.
Computed writable using the get and set pairs.
Computed just to generate value, not to run an action.
