I think symbols are more important for libraries code, where you would like others to prevent from overriding important properties of the interface you expose.

Short and simple explanation. But what about the case when you need to interpret the Symbols value at a later point in time. You will have to pass your original Symbol all the way alogn or you got the case that you might face several identically looking symbols with different values. Your original value was not overwritten but if the values are hash values, booleans or other equally looking values, it's still nearly impossible to know what value you'll have to refer to.

Correct me if I'm wrong but I don't see the huge benefit from using Symbols.

Nicely explained! Now I can go play with madness... 😉

What if another developer defines a symbol with the same name as you did? The problem is still there.

You are making different identifier they can be overwritten

Great video and explanation. TBH I don't see what value the Symbol type adds to JavaScript.

I still don't get it... you're creating new variables for each new symbol just like how in the first example you used "a" and 666. You can still change the value of "sym" from "secret" to something else, right? How is this any different?

What the hell...you are using different identifiers
