In short, prototype is an immensely powerful tool you can use in your coding. Once you understand how prototype inherits, and the chain of objects it inherits from, you can start to create some really advanced and powerful object combinations.
One reason to use the built-in prototype object is if you’ll be duplicating an object multiple times that will share common functionality. By attaching methods to the prototype, you can save on duplicating methods being created per each new instance.
It’s A “Bad” Part Because:
How many properties does a prototype object have?
prototype . As seen from the above image prototype property of the function is an object (prototype object) with two properties: constructor property which points to Human function itself.
Do objects prototype?
Do all functions have a prototype property?
Every function has the “prototype” property even if we don’t supply it. The default “prototype” is an object with the only property constructor that points back to the function itself. We can use constructor property to create a new object using the same constructor as the existing one.
