A set of useful static methods to deal with arrays; provide missing methods for older browsers.

+Clone a flat array without referencing the previous one. Note that this is different +from Ext.clone since it doesn't handle recursive cloning. It's simply a convenient, easy-to-remember method +for Array.prototype.slice.call(array)
+The array
+The clone array
+Checks whether or not the given array contains the specified item
Checks whether or not the given array contains the specified item
The array to check
+The item to look for
+True if the array contains the item, false otherwise
+Perform a set difference A-B by subtracting all items in array B from array A.
+Perform a set difference A-B by subtracting all items in array B from array A.

+B
+difference
+Executes the specified function for each array element until the function returns a falsy value. +If such an item is found, the function will return false immediately. +Otherwise, it will return true.
+Callback function for each item
+Callback function scope
+True if no false value is returned by the callback function.
+Creates a new array with all of the elements of this array for which +the provided filtering function returns true.
+Creates a new array with all of the elements of this array for which +the provided filtering function returns true.

+Recursively flattens into 1-d Array. Injects Arrays inline.
+Recursively flattens into 1-d Array. Injects Arrays inline.
+The array to flatten
+The new, flattened array.
+Iterates an array and invoke the given callback function for each item. Note that this will simply +delegate to the native Array.prototype.forEach method if supported. +It doesn't support stopping the iteration by returning false in the callback function like +each. However, performance could be much better in modern browsers comparing with +each
+The array to iterate
+The function callback, to be invoked these arguments:
+ +item: {Mixed} The item at the current index in the passed arrayindex: {Number} The current index within the arrayallItems: {Array} The array itself which was passed as the first argument(Optional) The execution scope (this) in which the specified function is executed.
Converts a value to an array if it's not already an array; returns:
+ +undefined or nullThe value to convert to an array if it's not already is an array
+(Optional) newReference True to clone the given array and return a new reference if necessary, +defaults to false
+array
+Push an item into the array only if the array doesn't contain it yet
+Push an item into the array only if the array doesn't contain it yet
+The array
+The item to include
+The passed array itself
+Get the index of the provided item in the given array, a supplement for the
+missing arrayPrototype.indexOf in Internet Explorer.
The array to check
+The item to look for
+(Optional) The index at which to begin the search
+The index of item in the array (or -1 if it is not found)
+Merge multiple arrays into one with unique items that exist in all of the arrays.

+Returns the maximum value in the Array
+Returns the maximum value in the Array
+The Array from which to select the maximum value.
+(optional) a function to perform the comparision which determines maximization.
+ + If omitted the ">" operator will be used. Note: gt = 1; eq = 0; lt = -1
+maxValue The maximum value
+Calculates the mean of all items in the array
+Calculates the mean of all items in the array
+The Array to calculate the mean value of.
+The mean.
+Returns the minimum value in the Array.
+Returns the minimum value in the Array.
+The Array from which to select the minimum value.
+(optional) a function to perform the comparision which determines minimization.
+ + If omitted the "<" operator will be used. Note: gt = 1; eq = 0; lt = -1
+minValue The minimum value
+Plucks the value of a property from each item in the Array. Example:
+ +Ext.Array.pluck(Ext.query("p"), "className"); // [el1.className, el2.className, ..., elN.className]
+The Array of items to pluck the value from.
+The property name to pluck from each element.
+The value from each item in the Array.
+Removes the specified item from the array if it exists
+Removes the specified item from the array if it exists
+The array
+The item to remove
+The passed array itself
+Executes the specified function for each array element until the function returns a truthy value. +If such an item is found, the function will return true immediately. Otherwise, it will return false.
+Callback function for each item
+Callback function scope
+True if the callback function returns a truthy value.
+Sorts the elements of an Array. +By default, this method sorts the elements alphabetically and ascending.

+The array to sort.
+(optional) The comparison function.
+The sorted array.
+Calculates the sum of all items in the given array
+Calculates the sum of all items in the given array
+The Array to calculate the sum value of.
+The sum.
+Converts any iterable (numeric indices and a length property) into a true array.
+ +function test() {
+ +var args = Ext.Array.toArray(arguments),
+ fromSecondToLastArgs = Ext.Array.toArray(arguments, 1);
+
+alert(args.join(' '));
+alert(fromSecondToLastArgs.join(' '));
+}
+ +test('just', 'testing', 'here'); // alerts 'just testing here';
+ + // alerts 'testing here';
+Ext.Array.toArray(document.getElementsByTagName('div')); // will convert the NodeList into an array +Ext.Array.toArray('splitted'); // returns ['s', 'p', 'l', 'i', 't', 't', 'e', 'd'] +Ext.Array.toArray('splitted', 0, 3); // returns ['s', 'p', 'l', 'i']
