bind、call、apply是JavaScript中Function.prototype非常重要的三个方法,他们的作用是改变this的指向。三者的区别是: bind返回一个函数,该函数改变了this的指向。call直接调用函数,也可以传递参数用逗号隔开。apply直接调用函数,也可以传递参数使用数组传递给第二个参数。
Otherwise, call_once invokesstd::forward<Callable>(f) with the argumentsstd::forward<Args>(args)... (as if bystd::invoke). Unlike thestd::threadconstructor orstd::async, the arguments are not moved or copied because they don't need to be transferred to another thread of execution. (suc...
