When editing javascript with Visual Studio code, I constantly get a useless and intrusive popup showing some kind of irrelevant method signature

It also does not disappear when typing. Even an escape will not delete it, but a click in some other code usually does.
My current user configuration is as follows
// Place your settings in this file to overwrite the default settings
{
"python.pythonPath": "/home/ivo/Atom/bin/python",
"python.linting.pylintEnabled": false,
"python.linting.flake8Enabled": true,
"python.unitTest.nosetestsEnabled": true,
"python.unitTest.nosetestPath": "bin/django",
"python.unitTest.nosetestArgs": ["test", "apps/"],
"python.unitTest.unittestEnabled": false,
"editor.acceptSuggestionOnEnter": false,
"editor.fontSize": 13,
"editor.renderControlCharacters": true,
"editor.useTabStops": false,
"editor.suggestOnTriggerCharacters": false,
"editor.wordBasedSuggestions": false,
"editor.quickSuggestions": false
}
