trait JSArrayOps[A] extends Object

Discouraged native JavaScript Array methods.

In general, you should prefer the Scala collection methods available implicitly through ArrayOps, because they are inlineable, and hence faster.

To enable the use of these functions on js.Arrays, import the implicit conversion JSArrayOps.jsArrayOps.

  2. abstract def jsEvery[T](callbackfn: ThisFunction3[T, A, Int, Array[A], Boolean], thisArg: T): Boolean

    The every method executes the provided callback function once for each element present in the array until it finds one where callback returns a falsy value (a value that becomes false when converted to a Boolean).

    The every method executes the provided callback function once for each element present in the array until it finds one where callback returns a falsy value (a value that becomes false when converted to a Boolean). If such an element is found, the every method immediately returns false. Otherwise, if callback returned a true value for all elements, every will return true. callback is invoked only for indexes of the array which have assigned values; it is not invoked for indexes which have been deleted or which have never been assigned values.

    callback is invoked with three arguments:

    - the value of the element - the index of the element - and the Array object being traversed.

    If a thisObject parameter is provided to every, it will be used as the this for each invocation of the callback. If it is not provided, or is null, the global object associated with callback is used instead.

    every does not mutate the array on which it is called.

    every acts like the "for all" quantifier in mathematics. In particular, for an empty array, it returns true. (It is vacuously true that all elements of the empty set satisfy any given condition.)

    filter calls a provided callback function once for each element in an array, and constructs a new array of all the values for which callback returns a true value.

    filter calls a provided callback function once for each element in an array, and constructs a new array of all the values for which callback returns a true value. callback is invoked only for indexes of the array which have assigned values; it is not invoked for indexes which have been deleted or which have never been assigned values. Array elements which do not pass the callback test are simply skipped, and are not included in the new array.

    callback is invoked with three arguments:

    - the value of the element - the index of the element - the Array object being traversed

    If a thisObject parameter is provided to filter, it will be used as the this for each invocation of the callback. If it is not provided, or is null, the global object associated with callback is used instead.

    filter does not mutate the array on which it is called.

    forEach executes the provided callback once for each element of the array with an assigned value.

    forEach executes the provided callback once for each element of the array with an assigned value. It is not invoked for indexes which have been deleted or which have been initialized to undefined.

    callback is invoked with three arguments:

    - the element value - the element index - the array being traversed

    If a thisArg parameter is provided to forEach, it will be used as the this value for each callback invocation as if callback.call(thisArg, element, index, array) was called. If thisArg is undefined or null, the this value within the function depends on whether the function is in strict mode or not (passed value if in strict mode, global object if in non-strict mode).

    reduce executes the callback function once for each element present in the array, excluding holes in the array, receiving four arguments: the initial value (or value from the previous callback call), the value of the current element, the current index, and the array over which iteration is occurring.

    The first time the callback is called, previousValue and currentValue can be one of two values. If initialValue is provided in the call to reduce, then previousValue will be equal to initialValue and currentValue will be equal to the first value in the array. If no initialValue was provided, then previousValue will be equal to the first value in the array and currentValue will be equal to the second.
