So, what actually __proto__ is?

This is a shorthand notation for the word prototype which can be considered as additional storage for an object, that contains the object’s metadata like some properties & methods.

ObjectName.prototype.FunctionName = function() { //this can have parameters as a normal function
 //function code
}
str.myCustomFunction()
