def findClosest(value: JsNumber, arr: Array[JsNumber]): Int

Snaps a value to the nearest value in an array.
Snaps a value to the nearest value in an array.
value
The search value
arr
The input array which must be sorted.
returns
The nearest value found.

def getRandomItem[T](objects: Array[T], startIndex: Int = js.native, length: Int = js.native): T

Fetch a random entry from the given array.
Fetch a random entry from the given array. Will return null if there are no array items that fall within the specified range or if there is no item for the randomly chosen index.
objects
An array of objects.
startIndex
Optional offset off the front of the array. Default value is 0, or the beginning of the array.
length
Optional restriction on the number of values you want to randomly select from.
returns
The random object that was selected.

def numberArray[T](start: JsNumber, end: JsNumber): Array[T]

Create an array representing the inclusive range of numbers (usually integers) in [start, end].
Create an array representing the inclusive range of numbers (usually integers) in [start, end]. This is equivalent to numberArrayStep(start, end, 1).
start
The minimum value the array starts with.
end
The maximum value the array contains.
returns
The array of number values.
def numberArrayStep[T](start: JsNumber, end: JsNumber = js.native, step: Int = js.native): Array[T]

Create an array of numbers (positive and/or negative) progressing from start up to but not including end by advancing by step.
Create an array of numbers (positive and/or negative) progressing from start up to but not including end by advancing by step. If start is less than end a zero-length range is created unless a negative step is specified. Certain values for start and end (eg. NaN/undefined/null) are currently coerced to 0; for forward compatibility make sure to pass in actual numbers.
start
The start of the range.
end
The end of the range.
step
The value to increment or decrement by.
returns
Returns the new array of numbers.

def removeRandomItem[T](objects: Array[T], startIndex: Int = js.native, length: Int = js.native): T

Removes a random object from the given array and returns it.
Removes a random object from the given array and returns it. Will return null if there are no array items that fall within the specified range or if there is no item for the randomly chosen index.
objects
An array of objects.
startIndex
Optional offset off the front of the array. Default value is 0, or the beginning of the array.
length
Optional restriction on the number of values you want to randomly select from.
returns
The random object that was removed.
def rotateLeft[T](array: Array[T]): Array[T]

Moves the element from the start of the array to the end, shifting all items in the process.
Moves the element from the start of the array to the end, shifting all items in the process. The "rotation" happens to the left.
array
The array to rotate. The array is modified.
returns
The rotated value.
def rotateMatrix[T](matrix: Array[T], direction: |[JsNumber, String]): Array[T]

Rotates the given matrix (array of arrays).
Rotates the given matrix (array of arrays).
matrix
The array to rotate; this matrix may be altered.
direction
The amount to rotate: the rotation in degrees (90, -90, 270, -270, 180) or a string command ('rotateLeft', 'rotateRight' or 'rotate180').
returns
The rotated matrix. The source matrix should be discarded for the returned matrix.

def rotateRight[T](array: Array[T]): Array[T]

Moves the element from the end of the array to the start, shifting all items in the process.
Moves the element from the end of the array to the start, shifting all items in the process. The "rotation" happens to the right.
array
The array to rotate. The array is modified.
returns
The shifted value.
def shuffle[T](array: Array[T]): Array[T]

A standard Fisher-Yates Array shuffle implementation which modifies the array in place.

array
The array to shuffle.
returns
