Tests whether this object has the specified property as a direct property.

Unlike js.Object.hasProperty, this method does not check down the object's prototype chain.

MDN

Tests whether this object is in the prototype chain of another object.

The join() method joins all elements of an array into a string.

separator Specifies a string to separate each element of the array. The separator is converted to a string if necessary. If omitted, the array elements are separated with a comma.

ECMAScript 6 JavaScript Iterator for this Array.

The slice() method returns a shallow copy of a portion of an array.

MDN

Sets the length of the array. If the new length is bigger than the old length, created slots are filled with undefined (irrespective of the type argument A!). If the new length is smaller than the old length, the array is shrunk.

The pop() method removes the last element from an array and returns that element.

MDN

Tests whether the specified property in an object can be enumerated by a call to js.Object.properties, with the exception of properties inherited through the prototype chain.

If the object does not have the specified property, this method returns false.

MDN

The push() method mutates an array by appending the given elements and returning the new length of the array.

MDN

The reverse() method reverses an array in place. The first array element becomes the last and the last becomes the first.

MDN

The shift() method removes the first element from an array and returns that element. This method changes the length of the array.

MDN

The sort() method sorts the elements of an array in place and returns the array. The sort is not necessarily stable. The default sort order is lexicographic (not numeric).

If compareFunction is not supplied, elements are sorted by converting them to strings and comparing strings in lexicographic ("dictionary" or "telephone book," not numerical) order. For example, "80" comes before "9" in lexicographic order, but in a numeric sort 9 comes before 80.

MDN

Removes and adds new elements at a given index in the array.

This method first removes deleteCount elements starting from the index index, then inserts the new elements items at that index.

If index is negative, it is treated as that number of elements starting from the end of the array.

The unshift() method adds one or more elements to the beginning of an array and returns the new length of the array.

MDN

Access the element at the given index.

concat creates a new array consisting of the elements in the this object on which it is called, followed in order by, for each argument, the elements of that argument (if the argument is an array) or the argument itself (if the argument is not an array).

MDN

Length of the array.

Set the element at the given index.
