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();
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.
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 //.
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.
