TypedArray.prototype.filter()

callbackFn

A function to execute for each element in the typed array. It should return a truthy value to keep the element in the resulting typed array, and a falsy value otherwise. The function is called with the following arguments:

element

The current element being processed in the typed array.

index

The index of the current element being processed in the typed array.

array

The typed array filter() was called upon.

thisArg Optional

A value to use as this when executing callbackFn. See iterative methods.

A copy of the given typed array containing just the elements that pass the test. If no elements pass the test, an empty typed array is returned.

See Array.prototype.filter() for more details. This method is not generic and can only be called on typed array instances.

The following example uses filter() to create a filtered typed array that has all elements with values less than 10 removed.

function isBigEnough(element, index, array) {
  return element >= 10;
}
new Uint8Array([12, 5, 8, 130, 44]).filter(isBigEnough);
// Uint8Array [ 12, 130, 44 ]
