method Float16Array.findLastIndex



Float16Array.findLastIndex(predicate: (value: number,
index: number,
array: Float16Array,
) => unknown,
thisArg?: any,
): number

Returns the index of the last element in the array where predicate is true, and -1 otherwise.

Parameters



predicate: (value: number,
index: number,
array: Float16Array,
) => unknown

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.

optional



thisArg: any

If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.

Return Type

number
