Javascript Arrays | Javascript Tutorial For Beginners
In this video series we are going to learn modern javascript from scratch. This video is recommended for anyone wanting to learn javascript the modern way with ES2015. No previous programming knowledge is required, so this video series will help you learn javascript as your first programming language.
We will also cover the basics of arrays and where to use them. The popular ones include using pop method to remove a value from the end of the array, push method to add a value to the end of the array. Shift is used to remove a value from the beginning of the array and unshift adds a value.
We are also going to take a look on what types of values we can store inside the array. How to access each value by its index and modify them as well.
Things covered in this video:
Basics of javascipt arrays.
How to add and remove values inside of an array.
How to modify a specific value of an array.
How to access each value.

Man you are a godsend! Super informative and fun, i love how you'll acknowledge things that are a little hard to get used to or don't make that much sense because someone like me, i will only fully understand something if i know WHY it is that way. I can't just put random info in my brain. Having someone like you say "yea this is kinda weird but we'll have to get used to it" is really reassuring and helps me memorize things so much. I got a school assignment which i have to learn JS for and to be honest, i'd rather be doing anything else. But somehow through your videos, i think i'm actually looking forward to it now! Thanks!

Ted, array starts at zero because the memory location of the whole array is the same of it's first element when the first element is zero. If it would start with one, the memory location for one is different than the array as a whole.

How can I pass an array to a function, as a SINGLE argument, and then access the elements of that array from within the function?

This is _not quite as applicable to Javascript_ because it is not a strictly typed language, but it serves to highlight _why_ arrays are indexed from [0] and why it is an (mostly) accepted standard. You may or may not know this, but for education purposes: Array index and [0] : An array (at least in classic programming terms) is allocated in contiguous (one-segment) of memory for whatever you may be storing in that array. So if you have an Array of numbers, the memory for that array will be allocated as: * A 'number' type takes up a certain amount of memory, lets pretend it takes up 32 bits per value (or as an Int32 for someone who may be familiar). Let's say you declare an array as follows: var myArray = [5, 7, 29, 43, 12]; The memory allocated for this array will be * = Now the variable "myArray" classically doesn't actually store the _entire_ array - it is what would be referred to as a *pointer* to the start of the allocated memory for that array. When you ask for an element inside the array (let's say you want the second number) you specify the _offset_ from the beginning of the memory block. An offset of _0_ would give you the first element, and offset of _1_ would give you the second, and so forth. This is calculated when you specify the index as _myArray[1]_ as follows: + ( * ) = In the case of our example it would be + ( * ) = so in our example: myArray[1] = 7 I hope this helps someone who was wondering why [0] is the index. Now this example gets a little wonky once you start realizing that it only applies to strictly typed languages that allocates memory for _types_ and doesn't treat everything in the language as an underlying type of _object_ like many modern programming languages do, but know that behind the scenes, the C/C++/whatever the code base is, is probably doing this; what you're seeing is a representation of this functionality extended into a syntactical standard. Also, you may be thinking "but strings aren't the same size" : this is because string arrays are allocated as two-dimensional arrays of characters.

5:24 ! The more efficient way :- This is our array => const arr = [ 1, 2, 3 ]; You know you gotta count them from 0 that means 0 corresponds to 1! The first element(1). If you wanna select 1 then you just can input the value i.e element.at(); The whole thing is gonna look like: // Input const arr = [1, 2, 3].at(0); console.log(arr); // Output = 1

Why indexes starts from 0? I think it is because they answer the question: on which item am I looking at after the 1st one? (and not: at which item in the order I am looking at [at the moment]). It is just more hardware point of view instread of human one. What I read on Internet is also that the calculations on indexes are easier this way.
