Get results and fix problems
If an inspection has detected a problem in your code, you can quickly apply a fix in the editor. Place the caret at the highlighted piece of code and press Alt+Enter.
WebStorm shows an interactive preview next to the quick-fix for some inspections for example, Assignment used as condition, Unreachable 'case' branch of a 'switch' statement, Assignment used as condition, and others. You can hide and show this preview by pressing Ctrl+Q.
Fix all occurrences of a problem in the current file
If a detected problem occurs several times in a file, WebStorm suggests fixing them all at once.
Place the caret at the highlighted piece of code and press Alt+Enter.
Select the relevant fix and then select Fix all "<problem description>" in file from the list.
Apply fixes in the Problems tool window
If you have invoked inspections manually, you can examine the results in the Problems tool window that opens automatically after the analysis is finished. All detected problems are listed in the left part of the tool window. Click a problem to display inspection details on the right.
To fix a problem, click the
icon on the toolbar or in the context menu. You can also press Alt+Enter and select a suitable fix from the popup menu.
If a problem occurs several times in a file, you can fix all the occurrences at once. Select the problem description, click
icon on the toolbar, select the relevant fix, and then select Fix all "<problem description>" in file from the list.
Clean up your code
You can streamline the process of fixing problems in your code by running Code Cleanup. This allows you to batch-apply quick-fixes to the selected scope without examining each problem individually.
During the cleanup, the IDE applies fixes from the code cleanup inspections in the selected inspection profile. To view the list of these inspections, open the Settings dialog by pressing Ctrl+Alt+S and go to , click 
, and enable the Show only cleanup inspections option.
Batch-apply quick-fixes (Code Cleanup)
In the main menu, go to .

You can also click Configure to view all code cleanup inspections and their settings.
Click Analyze to launch the cleanup.
WebStorm performs code analysis and applies quick-fixes from the selected inspection profile to the detected issues.
