Float64Array.prototype.find

Returns the value of the first element in the typed array where predicate is true, and undefined otherwise.

Syntax

find(predicate, thisArg?)

Parameters

• predicate function(value, index, array)

  A function that accepts up to three arguments. The find method 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, find immediately returns that element value. Otherwise, find returns undefined.

• thisArg optional

  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 value

An array element or undefined.

Example

new Float64Array([1, 2, 3, 4, 5]).find(x => x > 2)
