method Int32Array.findIndex
Private
Int32Array.findIndex(
predicate: (
value: number,
index: number,
) => boolean,
thisArg?: any,
): number

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

Parameters

predicate: (
value: number,
index: number,
) => boolean

find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, findIndex immediately returns that element index. Otherwise, findIndex 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
