The more I try to understand "this" the more my brain wants to fall out of my head.

I understood because I read the book You Don't Know Javascript, but I think you should slow down a bit for newer people, otherwise I found it well made, really love this series you're doing.

Let me re-arrange some sections to make it a bit clearer and beginner friendly: var o = {a: 1, b: 3}; function add(c, d) { return this.a + this.b + c + d; } console.log(add.call(o, 5, 7)); console.log(add.apply(o, [10, 20])); It's good practice to declare all your variables and values first before any functions and by doing this, it becomes easier to read. Here we create an object with two properties which is "a and b". "a" set to 1 and "b" set to 3. "this.a" and "this.b" is pointing to the properties of the variable "o". apply and call are METHODS for the "this" keyword, think of them as attachments for your gun that enables it to do other stuff. the rest should be self explanatory if you studied the basics well. If not, gotta go back to start, you might have missed a few lessons.

I really would like to grasp these concepts, but it seems as though JavaScript is some sort of 'bottomless pit' of information that cannot be explained in a simplistic terminology. Thereby leaving a beginner unsure about what one learns.

you haven't answered the main question: Why TF do we need "this" in the first place? It does absolutely nothing. Is it some sort of inside joke?

this has to be the least beginner friendly tutorial on the subject. I feel like I have to be a brain surgeon to follow along.

You have not simplified the issue ,but thank you for the video

If you listen very carefully, the first 14 seconds explain a lot! " The value of 'this' when used in a function, is the object that owns the function"

When Beau says 'Created' about O (When talking about arrow functions around minute 7), does created mean when it is first called ? Intuatively, I would have thought, it was created in the O object.

Complicated example. Must use easy to understand parameters.

for someone who's starting in JS this video was very fast, I find it a little hard to understand.

Many thanks for this serious video about the subject far away from the "hello world" ones , one should be concentrated , stop and replay to get the best of the video , thank you again

Loving this video

Great info! Understanding core JavaScript is so important... its more important than learning frameworks.

Bad way to teach. I had to stop the video halfway to avoid complications. Slow down and put the learner in mind next time.

I think this video misses structure as well as the point: Why? How "this" is interpreted depends on when it gets "resolved" so to speak. If you would have explained why it gets when resolved, one wouldnt need to store all this empty knowledge in his/her brain but rather would understand the underlying concept, which is less amout of data and way more powerful.

Excellent explanation, I loved it

too fast, too advance. your reference is mdn and I thought that this video will give me a best explanation but I was wrong

Thanks for this!

Which editior are you using

Didn't understand sheet

short time best explanation.

Lmao i thought i had understood but then i read the comments and obviously i didn´t understand

great stuff beau just a question - I read that if you have a method within an object and inside that object you've got 2 functions, the second function will lose the this context and will refer to the global object (the var that = this shtick)

great lesson!

This is very helpful thanks

Yes it was fast, but there is a pause button for that. Thanks for explaining THIS in its various contexts. It's not the definite guidebook, but it was very helpful to me!!!

Thank you!

Great upload!

Very neat explanation for 8:47 video thanks!

Not the best explanation of "this". "You Don't Know JS" is where you need to read.

Eureca! Thank you for this movie. I have got it!

Slow down & get a new mouse lol. But thanks for the help.

can anyone tell me why i am getting o.f() is undefined instead of value 8 ??

Great stuff

Thank you, but you need to slow down much more. I kept getting lost and eventually stopped at the half-way point.

My head spinned the 1st time I watched, but I could I understand it in the 2nd run. Thanks!

great, great, great

this tutorial is so confusing

what program are u using ?

thanks

This was confusing.

those mouse clicks are so loud I had to stop 1 minute in the video because it's distracting from the subject

Just stop clicking

Worse explanation ever! It confused me more.

This video could save a whole day wasted in 8 minutes

worst among the most incompetent people who tried to explain this.

JavaScript is disgusting. Utterly disgusting!

thanks but i hate it

most confusing tutorial...
