Inheritance =========== ```Example from 2 languages: JavaScript, TypeScript class B {} class A extends B {} ``` ```Example from 1 languages: Python class SumComputer(object): def __init__(self, a, b): self.a = a self.b = b def transform(self, x): raise NotImplementedError def inputs(self): return range(self.a, self.b) def compute(self): return sum(self.transform(value) for value in self.inputs()) class SquareSumComputer(SumComputer): def transform(self, x): return x * x class CubeSumComputer(SumComputer): def transform(self, x): return x * x * x ``` ```Example from 1 languages: Toit class Foo extends Bar: ``` ```Example from 1 languages: Speedie class Person (Animal) ``` * Languages *with* Inheritance include JavaScript, Python, Java, PHP, TypeScript, Scala, CoffeeScript, Dart, Pug, Chapel, Groovy, C3, SystemVerilog, Twig, Toit, spider, Apex, SpiderBasic, Aardvark, JS++, Speedie, Simula 67 * Languages *without* Inheritance include Lil, progsbase * View all concepts with or missing a *hasInheritance* measurement http://pldb.info/../lists/explorer.html#columns=rank~id~appeared~tags~creators~hasInheritance&searchBuilder=%7B%22criteria%22%3A%5B%7B%22condition%22%3A%22null%22%2C%22data%22%3A%22hasInheritance%22%2C%22origData%22%3A%22hasInheritance%22%2C%22type%22%3A%22num%22%2C%22value%22%3A%5B%5D%7D%5D%2C%22logic%22%3A%22AND%22%7D missing http://pldb.info/../lists/explorer.html#columns=rank~id~appeared~tags~creators~hasInheritance&searchBuilder=%7B%22criteria%22%3A%5B%7B%22condition%22%3A%22!null%22%2C%22data%22%3A%22hasInheritance%22%2C%22origData%22%3A%22hasInheritance%22%2C%22type%22%3A%22num%22%2C%22value%22%3A%5B%5D%7D%5D%2C%22logic%22%3A%22AND%22%7D with * Read more about Inheritance on the web: 1. https://en.wikipedia.org/wiki/Inheritance_(object-oriented_programming) 1.
