JavaScript Array Methods

The JavaScript method toString() converts an array to a 
string of (comma separated) array values.
Result:
The join() method also joins all array elements into a string.
It behaves just like toString(), but in addition you can specify the separator:
Result:
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.
The pop() method removes the last element from an array: 
The pop() method returns the value that was "popped out":
The push() method adds a new element to an array (at the end):
The push() method returns the new array length:
Shifting is equivalent to popping, but 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 shift() method returns the value that was "shifted out":
The unshift() method adds a new element to an array (at the beginning), and "unshifts" 
older elements: 
The unshift() method returns the new array length.
Array elements are accessed using their index number:
Array indexes start with 0:
[0] is the first array element[1] is the second[2] is the third ...
The length property provides an easy way to append a new element to an array:
Array elements can be deleted using the JavaScript operator delete.
Using delete leaves undefined holes in the 
array.
Use pop() or shift() instead.
The concat() method creates a new array by merging (concatenating) 
existing arrays:
The concat() method does not change the existing arrays. It always returns a new array.
The concat() method can take any number of array arguments:
The concat() method can also take strings as arguments:
The splice() method adds new items to an array.
The slice() method slices out a piece of an array.
The splice() method can be used to add new items to an array: 
The first parameter (2) defines the position where new elements should be 
added (spliced in).
The second parameter (0) defines how many elements should be
removed.
The rest of the parameters ("Lemon" , "Kiwi") define the new elements to be
added.
The splice() method returns an array with the deleted items: 
With clever parameter setting, you can use splice() to remove elements without leaving 
"holes" in the array: 
The first parameter (0) defines the position where new elements should be 
added (spliced in).
The second parameter (1) defines how many elements should be
removed.
The rest of the parameters are omitted. No new elements will be added.
The slice() method slices out a piece of an array into a new 
array.
This example slices out a part of an array starting from array element 1 
("Orange"):
The slice() method creates a new array.
The slice() method does not remove any elements from the source array.
This example slices out a part of an array starting from array element 3 
("Apple"):
The slice() method can take two arguments like slice(1, 3).
The method then selects elements from the start argument, and up to (but not 
including) the end argument.
If the end argument is omitted, like in the first examples, the slice() 
method slices out the rest of the array.
JavaScript automatically converts an array to a comma separated string when a 
primitive value is expected.
This is always the case when you try to output an array. 
These two examples will produce the same result:
All JavaScript objects have a toString() method.
There are no built-in functions for finding the highest 
or lowest value in a JavaScript array.
You will learn how you solve this problem in the next 
chapter of this tutorial.
Sorting arrays are covered in the next chapter of this tutorial.

const fruits = ["Banana", "Orange", "Apple"];
