The predicate function to apply to the values.
The index of the first element in the range to be
searched, inclusive. The default value is -1. Negative values
are taken as an offset from the end of the array.
The index of the last element in the range to be
searched, inclusive. The default value is 0. Negative values
are taken as an offset from the end of the array.
The index of the last matching value, or -1 if no
matching value is found.
If start < stop the search will wrap at the front of the array.
Linear.
A start or stop which is non-integral.
Modifying the length of the array while searching.
import { ArrayExt } from '@lumino/algorithm';
function isEven(value: number): boolean {
return value % 2 === 0;
}
let data = [1, 2, 3, 4, 3, 2, 1];
ArrayExt.findLastIndex(data, isEven); // 5
ArrayExt.findLastIndex(data, isEven, 4); // 3
ArrayExt.findLastIndex(data, isEven, 0); // -1
ArrayExt.findLastIndex(data, isEven, 0, 1); // 5
