Disable JetBrains Inspections and get the ESLint plugin.

The only thing that File | Invalidate caches and restart does for me is reset it long enough to trick me into thinking the error is gone. Once the inspections run again the error comes back like a gift that keeps on giving.

I saved myself all that frustration by disabling all JetBrains inspections (Editor > Inspections > uncheck JavaScript) Then I installed the ESLint plugin.

The inspection that causes "Unresolved function method" can be turned off by going to JetBrains inspections (Editor > Inspections > JavaScript) and searching for "Unresolved Javascript" and turning off "Unresolved Javascript function" and "Unresolved Javascript variable"

I killed them all and have edited my code hassle free ever since.
