This explanation of symbols finally made click. Thanks!

[@pandabuddy1655]

Mr, thank you Very much!

[@rajeshsahu3073]

Thank you so much for making a video on symbols.. I have only requested for symbols few weeks ago..

[@rylaczero3740]

I also remember reading that request in comments section.

[@user-mi8yj3lc4i]

Well explained. Thank you, sir.

[@vladislavamarkova8379]

Perfect explanation! This is the video that helped me grasp the very concept of symbols and their main usage. Thank you!

[@AllThingsJavaScript]

Glad it was helpful!

[@alaztetik2891]

Great explanation and examples!
Thank you Steve! 🚀

[@AllThingsJavaScript]

Glad it helped!

Thank you for this perfect video

[@AllThingsJavaScript]

Glad you liked it!

[@devins3711]

thank you so much for this thorough explanation! Liked & sub'd!

[@user-zb5jp4ti1d]

thanks Steve for putting these together.. i have quick query... why do keys in objects/dictionaries(Python) need to be hashable. what does that mean... would you pls, when you can, create a video that speaks to this subject of hash maps. thank you once again.

[@AllThingsJavaScript]

Will add it to the list.

[@jareddunlop8411]

I like the pace of this. I am confused by the common variable name of 'symb1' at line 1 and [symb1] inside object on line 6. Do you first have to make a symbol before you can use it as an object property, or is it just coincidence you named them the same.
In other words, could you have just the same done [dog] inside of the object, or do you have to explicitly create it first? ... const dog = Symbol();

[@AllThingsJavaScript]

At line 1 I create a symbol and store it in symb1. Then I use that symbol inside the object as the key for that key/value pair.

[@KASANITEJ]

does uuid and symbols both are same?

[@AllThingsJavaScript]

Not sure if symbols use uuid, but it is the same idea.

[@chetanpl]

Simple Q where we can use it?give me idea.

[@AllThingsJavaScript]

You would use a symbol as the property for an object similar to how you use a string for that purpose.

[@chetanpl]

If interviwer ask me why you would use it give me an scanerio requirement.

[@Deefamily1]

Okay I need more help I'm just teaching myself. I don't know if I'm asking the right question...by symbols. I mean a video explaining these ( ) and " " and [ ] and //.

[@AllThingsJavaScript]

These can be used for different things in JavaScript. For example, () can be used to group, to invoke a function, to define a method. So it depends on where it is used in the code. [] also have multiple applications. I would approach it by learning how to do different things with JavaScript.

What is your next coding video? Keep it up! Would you like to be TH-cam friends?

spammer

[@TroenderTass]

thanks, i think this must be one of the most useless programming functions i've ever encountered

[@lailanashim274]

Well, the point is: its worthless waste your time in it hahaha

[@haciendadad]

What a bad name for this useless function
