`[object ${t}]`, isArray: (v) => getType('Array')(v), isObject: (v) => getType('Object')(v), isFunction...这里是为了兼容第三方promise库,例如:q es6-promise if ((x && isObject(x)) || isFunction(x)) { try { const...then = x.then // 确定then是一个函数的时候,那么肯定是一个promise if (isFunction(then)) { // 执行then...onFulfilled : v => v onRejected = isFunction(onRejected) ?...promises.filter(item => isObject(item) && isFunction(item.then)) : [] return new Promise((resolve
利用isfunction进行判断 Python的inspect模块包含了大量的与反射、元数据相关的工具函数,isfunction就是其中一种,使用方法如下: from inspect import isfunction...# 判断成功 if(isfunction(add)): print add(5, 5) 4.

要不然容易出现未知的问题 3、define、require在打包之后不一定会暴露到window对象上来,可以手动暴露一下 完整代码: (function() { var _ = { isFunction..._.isFunction(foo) || foo....function catArgs() { return [].slice.call(arguments).map(function(fun) { return _.isFunction...function uncatArgs() { return [].slice.call(arguments).map(function(fun) { return _.isFunction..._.isFunction(_fun) || _fun.
