Heir
Helper functions for prototypical inheritance in JavaScript.
Use the source code and JSDoc comments as documentation, here's a quick example to get you started.
const heir = require('heir')
// Create the base class.
function Base() {}
// Add a method.
Base.prototype.foo = function () {
return 'Base#foo'
}
// Create a sub class which inherits from base.
function Sub() {}
heir.inherit(Sub, Base)
// Mix in some functionality enhancing objects.
heir.mixin(Sub, events)
heir.mixin(Sub, pooling)
// Change the original method.
Sub.prototype.foo = function () {
return [
'Sub#foo',
Sub._super.foo.call(this)
].join(', ')
}
// Create an instance of Sub and call it's method.
const s = new Sub()
s.foo() // Returns "Sub#foo, Base#foo"
