Here is a list of the methods of the Array object along with their description.

• CONCAT(): Returns a new array comprised of this array joined with other array(s) and/or value(s).
• every(): Returns true if every element in this array SATISFIES the provided testing function.
• filter(): Creates a new array with all of the elements of this array for which the provided filtering function returns true.
• forEach(): Calls a function for each element in the array.
• indexOf(): Returns the first (least) index of an element within the array equal to the specified value, or -1 if none is FOUND.
• join(): Joins all elements of an array into a string.
• lastIndexOf(): Returns the last (greatest) index of an element within the array equal to the specified value, or -1 if none is found.
• map(): Creates a new array with the results of calling a provided function on every element in this array.
• pop(): Removes the last element from an array and returns that element.
• push(): Adds one or more elements to the end of an array and returns the new LENGTH of the array.
• reduce(): Apply a function simultaneously against two values of the array (from left-to-right) as to reduce it to a single value.
• reduceRight(): Apply a function simultaneously against two values of the array (from right-to-left) as to reduce it to a single value.
• reverse(): Reverses the order of the elements of an array -- the first becomes the last, and the last becomes the first.
• shift(): Removes the first element from an array and returns that element.
• slice(): Extracts a section of an array and returns a new array.
• some(): Returns true if at least one element in this array satisfies the provided testing function.
• toSource(): Represents the source code of an object
• sort(): Sorts the elements of an array
• splice(): Adds and/or removes elements from an array.
• toString(): Returns a string representing the array and its elements.
• unshift(): Adds one or more elements to the FRONT of an array and returns the new length of the array.
