More on JavaScript Array Objects
(Page 1 of 5 )
Thanks for dropping by for another episode of our series on JavaScript Array Objects. We left off discussing five of the thirteen array objects JavaScript has to offer. Here, in this issue, we will make an effort to cover the remaining eight.
Just to recap, we previously discussed the concat() object, which allows us to join two or more arrays together and return the result. We also talked about join(), a handy dandy object that places every element in a given array into a delimiter separated string (you get to pick the delimiter).
Another object we previewed was pop(). We used it to remove and return the last or rightmost element in an array. We covered its counter as well, the push() object, which was used to add one or more elements to the right most or end of an array, and return the modified length of the array. Lastly, we learned how to reverse the order of the elements in our array with our good buddy, the reverse() object.
Before we pick up where we left off, here is a table showcasing our JavaScript objects:
Method | What It Does |
concat() | Used to join two (or more) arrays together and return the result. |
join() | Used to place every element of an array into a delimiter separated string. You specify the delimiter. |
pop() | Used to remove and return the right most (the last) element in an array. |
push() | Used to add one (or more) elements to the right most (end) of an array and then returns the modified array length. |
reverse() | Used to reverse the order of the elements in a given array. |
shift() | Used to remove the left most (first) element in an array and return it. |
slice() | Used to return given elements from an array. |
splice() | Used to remove or add elements to/from an array. |
sort() | Used to sort the elements within an array. |
toSource() | Represents an object's source code. |
toString() | Used to convert an array to a string. Returns the result. |
unshift() | Used to add one (or more) elements to the left side (beginning) of an array and returns the modified array length. |
valueOf() | Used to retrieve the primitive value of an array object. |
