WinJS.Namespace.log function

Writes output to the JavaScript console in Microsoft Visual Studio. You can provide an implementation of this method yourself, or use WinJS.Utilities.startLog to log to the JavaScript console.

Parameters

Remarks

The WinJS.log function is left for you to implement for performance purposes. The following code shows how to start logging and write to the log.

WinJS.Utilities.startLog({type: "customType", tags: "custom" });

WinJS.log && WinJS.log("starting up", "custom", "customType");
