javaScript Arrays Sort Methods | Learn and Code
Methods:
The JavaScript method toString() converts an array to a string of (comma separated) array values.
The join() method also joins all array elements into a string.
It behaves just like toString(), but in addition you can specify the separator
When you work with arrays, it is easy to remove elements and add new elements.
This is what popping and pushing is:
Popping items out of an array, or pushing items into an array.
JavaScript is one of the most popular programming languages in 2020. A lot of people are learning JavaScript to become front-end and/or back-end developers.
The pop() method removes the last element from an array
The push() method adds a new element to an array (at the end)
Shifting is equivalent to popping, working on the first element instead of the last.
The shift() method removes the first array element and "shifts" all other elements to a lower index.
The length property provides an easy way to append a new element to an array
