Suspicious variable/parameter name combination

Reports an assignment or a function call where the name of the target variable or the function parameter does not match the name of the value assigned to it.

Example:

  var x = 0;
  var y = x;

  var x = 0, y = 0;
  var rc = new Rectangle(y, x, 20, 20);

Here the inspection guesses that x and y are mixed up.

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | JavaScript and TypeScript | Probable bugs

Specify the names that should not be used together. An error is reported if a parameter name or an assignment target name contains words from one group while the name of the assigned or passed variable contains words from another group.
