web api instance property
PerformanceScriptTiming: sourceCharPosition property
Limited availability
The sourceCharPosition read-only property of the PerformanceScriptTiming interface returns a number representing the script character position of the script feature that contributed to the long animation frame (LoAF).
It is important to note that the reported function location will be the “entry point” of the script, that is, the top level of the stack, not any specific slow sub-function. See sourceFunctionName for more discussion around this.
Value
A number. Returns -1 if the script character position was not found.
Examples
See Long animation frame timing for examples related to the Long Animation Frames API.
