Redundant 'await' expression
Reports a redundant usage of await, such as await await, or awaiting a non-promise result.
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.
ES6RedundantAwait- 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.
When the 'Report for promises' option is selected, suggests removing await before promises when applicable (in return statements, and with Promise.resolve/reject).
Removing await in such contexts causes two problems.
Surrounding your code with
try-catchand forgetting to addawaitwill change code semantics while you may fail to notice that.Having an explicit
awaitmay prevent the V8 runtime from providing async stack traces.
