Intention actions
As you work in the editor, WebStorm analyzes your code, searches for ways to optimize it, and detects potential and actual problems.
As soon as the IDE finds a way to improve your code, it displays a yellow bulb icon 
in the editor next to the current line. By clicking this icon, you can view intention actions available in the current context. Intention actions cover a wide range of situations from warnings to optimization suggestions.
A yellow bulb icon also indicates that WebStorm has detected a problem and prompts you with a quick-fix for it. For severe problems, WebStorm displays a red bulb with an exclamation mark 
instead of a light yellow one . WebStorm suggests the first available quick-fix in an inspection tooltip, which appears every time you hover over a warning or an error.
See Configuring Inspection Severities and Code inspections for details.
You can open a full list of intention actions in the Settings/Preferences dialog, view their descriptions, and disable or enable them as described in View all intention actions below.
