js 实现洋葱模型、洋葱反向模型

洋葱反向模型

(function(){function fun(cb){console.log('fun->1');return ()=>{console.log('fun->2');cb()}}function fun2(cb){console.log('fun2->1');// return ()=>{//     console.log('fun2->2');//     cb()// }}function fun3(cb){console.log('fun3->1');return ()=>{console.log('fun3->2');cb()}}console.log('start');const ff = fun(fun2(fun3(()=>{console.log('end');})))ff()
})()
