Thanks for this. We often joke about the weird quirks of JS but rarely get explanations

I'm honestly kind of tempted to go through the entire infamous Wat video and break down all the different parts of it.

Also, I think you read this before the most recent update that should clear up a few of the lingering questions one might have (such as "But if they're both objects, why does one evaluate to "[object Object]" and the other evaluate to an empty string? What's the heck?!"

// object to string
({}) instanceof Object // true
Object.prototype.toString.call({}) // "[object Object]"
([]) instanceof Array // true
Object.prototype.toString.call([]) // "[object Array]"
// "inheritance"
Array instanceof Object // true
Object instanceof Array // false
// array to string
[1,2].join(",") // "1,2"
[1,2].toString() // "1,2"
