 ### Formatting {/*formatting*/}
 
-The last thing you want to do when sharing your code with another contributor is get into an discussion about [tabs vs spaces](https://www.google.com/search?q=tabs+vs+spaces)! Fortunately, [Prettier](https://prettier.io/) will clean up your code by reformatting it to conform to preset, configurable rules. Run Prettier, and all your tabs will be converted to spaces—and your indentation, quotes, etc will also all be changed to conform to the configuration. In the ideal setup, Prettier will run when you save your file, quickly making these edits for you.

+* `phase`: `"mount"`, `"update"` or `"nested-update"`. This lets you know whether the tree has just been mounted for the first time or re-rendered due to a change in props, state, or Hooks.
 * `actualDuration`: The number of milliseconds spent rendering the `<Profiler>` and its descendants for the current update. This indicates how well the subtree makes use of memoization (e.g. [`memo`](/reference/react/memo) and [`useMemo`](/reference/react/useMemo)). Ideally this value should decrease significantly after the initial mount as many of the descendants will only need to re-render if their specific props change.
 * `baseDuration`: The number of milliseconds estimating how much time it would take to re-render the entire `<Profiler>` subtree without any optimizations. It is calculated by summing up the most recent render durations of each component in the tree. This value estimates a worst-case cost of rendering (e.g. the initial mount or a tree with no memoization). Compare `actualDuration` against it to see if memoization is working.
 * `startTime`: A numeric timestamp for when React began rendering the current update.
