How to read Ecmascript specification? (with examples) | The specification behind Javascript

[@madsemicolon]

You just killed my fear of these weird docs!! Please make more videos.

[@saurabhkacholiya]

Thanks a lot, man. I have recently got excited about how JS works after reading 1st 3 books YDKJS. This video has helped me a lot to read specification better!

[@Temple_Cloud]

Really enjoyed this video. A nice intuitive introduction with concrete examples. Thanks!

[@chiragr1336]

Thanks allot. We need more such videos. Don't quit. I think you'll have allot of subscribers. Only content matters.

[@bendtherules0]

Thanks for the encouragement. Yes, I am not making a lot of videos - but don't worry, I am also not going to quit.

[@kushalthapa2865]

Highly appreciate it. Myan people like you makes me learn more. Inspiring. Cover more topics from ECMA.

[@bendtherules0]

Thanks. Are you interested in any specific topic? Made a new video about array literals and rest operator. Will make some about object and functions later.

[@kushalthapa2865]

@@bendtherules0 Sorry for late reply. I have been programmer for past few years. I don't have problem with language but ES6 documentation sucks. I hope you will enlighten on ES6 documentation.👏👏

Hi your are explaining from the source. I didn't find such explanation on udemy. I just strated learning but i prefer going to source for learning. Good job appreciate your efforts 👏. Thank you

[@chiragr1336]

Anyone who doesn't feel they understand pls read the first three parts of YDKJS series. And build some react apps. And try to understand relationship between js and ecmascript. You should be good go then.

Great video.

[@rajdeepchandra9807]

so this ToObject is similar to autoboxing feature right? Like the way it wraps any primitive datatype into a shadow object whenever you try to calculate length or other things.

[@bendtherules0]

Yes, exactly. It's great that you commented, because i just checked how autoboxing works in spec. When you try to access any property from either primitive or object, first it does ToObject and then accesses that property key from the object. So, basically this same ToObject gets called which converts primitives and passes object through. Link - tc39.es/ecma262/#sec-getv (GetV is called when you access any property like "hello". length)

[@shubhamlodhi7641]

Thanks bro. I have one doubt . When i go through documentation. I have seen many new things which is hard to understand [[these type of box]]. What does it mean. How can i start understanding. Thanks for the your effort to share about this!

[@bendtherules0]

Those are called internal slots or fields. Just think of them as a internal functions or values - they are not exposed directly to Javascript, but used by other parts of the spec.

[@shubhamlodhi7641]

@@bendtherules0 ohh thanks. This will helps as to start

[@chiragr1336]

@bendtherules pls make video on how to start understanding react source code.

[@bendtherules0]

Hi Chirag, thanks for the suggestion. I'll try to read the source code later and see how it goes. In the meantime, you might like react internal related videos from The Internals channel - like kzbin.info/www/bejne/rouwqKGQn9uNl5I. There is also one on react hooks internal.

[@chiragr1336]

@@bendtherules0 thanks allot. I never come across these channels in the search and yet that's exactly what I was searching for. Even your channel I found in LinkedIn. I think subscriber count is overrated.
