Keeping Track of 'This' in JavaScript

In Java, the special variable "this" is used to refer to an object. But following which object "this" refers to depends on the code you're executing and how "this" is used. In this JavaScript teaser, we help you keep track of a coding variable more slippery than a banana peel.

Excellent tutorial of ```this``` keyword. Googled a lot for a better explanation on ```this``` keyword, but this is the best explanation one can get.

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.

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

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?

I feel like that first "banana slip" is more of a scope issue, than a THIS issue.

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?

[blackviking]

Excellent video. Just want a banana now....

I can't hear anything is it muted?

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.

I recommend not covering the code with "the results". It makes it difficult to look back and forth and compare.
