function
jsc.reoptimizationRetryCount
func: (...args: any[]) => any
): number;
Returns how many times JavaScriptCore has thrown away a function's optimized code because the assumptions it was compiled with turned out to be wrong (for example, a function that was only ever called with integers is called with a string), forcing the function to be optimized again. Each retry doubles how long the function has to run before it is optimized again, so a function with a high count is being deoptimized repeatedly.
Returns 0 for functions that have not been compiled by the baseline JIT yet.
