So I have a question... Which procedure to follow to call a function which is not part of a obj. Sending this as an argument or using .call(). And the must answer question would be.. Why to opt for that solution rather than other one?
Method is a function within an object. From example below... "myFunction" is a method of "x". var x = { myFunction: function() { console.log('hello") } }
triforcelink "this" in JS is not the same as "self" in Python. In JS the value of "this" changes depending on how the function was called. You actually can't always tell what the value of "this" is without looking at how the function was called. There are 5 different rules, view the video for examples.
Thank you so much. I have been struggling in understanding the concept of "this" f. It's solved within just 13 mins by watching this video.
Excellent tutorial of ```this``` keyword. Googled a lot for a better explanation on ```this``` keyword, but this is the best explanation one can get.
My sincere and appreciative thanks for giving a pretty thorough explanation of such a mysterious and at times, misunderstood feature in JS.

leave it to o'reilly to make things even more confusing

I feel like that first "banana slip" is more of a scope issue, than a THIS issue.
Well Explained!!
One little suggestion: if the cursor is able to point at the words corresponding to the voiceover, it would be more helpful.
What is the difference between methods and functions in JavaScript? Is the method and object same thing here?
Method is a function within an object. From example below... "myFunction" is a method of "x".
var x = {
myFunction: function() {
console.log('hello")
}
}
I can't hear anything is it muted?
Excellent video. Just want a banana now....
'This' is interesting!
nice one
You speaking way to fast about this topic, when there is so many redundant words its really hart to grasp the concept.
'this' is a lot similar to 'self' from other languages like python.
This is reffering to the object, as in other programming languages. You are correct :P
+triforcelink Why no one said this to me before, they all act like "this" is a very unique feature? ;_;

this is only similar to Python's self when you're using it from inside a constructor function where this(like self) refers to the newly created object
I recommend not covering the code with "the results". It makes it difficult to look back and forth and compare.
