call 和 apply 有什么区别

apply

• invoke the function with arguments as an array 数组做参数

theFunction.apply(valueForThis, arrayOfArgs)

call

• requires the parameters be listed explicitly 直接值做参数

theFunction.call(valueForThis, arg1, arg2, ...)

A useful mnemonic is "A for array and C for comma"

What is the difference between call and apply?
