Symbol
Uint8Array.findLastIndex
findLastIndex(predicate: (value: number, index: number, array: this) => unknown, thisArg?: any): number
@param predicate
findLastIndex calls predicate once for each element of the array, in descending order, until it finds one where predicate returns true. If such an element is found, findLastIndex immediately returns that element index. Otherwise, findLastIndex returns -1.
@param thisArg
If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
