functions, then write multiple Mixin class Then, it does not depend on the implementation of the subclass Finally, subclasses can still work even if they do not inherit the Mixin class, which is missing a function. (such as the aircraft can still carry passengers, just can't fly ^_^) In addition, Reactjs also has a mixin function, and the syntax is simple:var planemixin = function () { return { fly:function () { console.log (' I am Flying'); } = React.createclass ({
