Apply method in Javascript

The official explanation of the apply method is:
Apply a method of an object and replace the current object with another object.
Apply ([thisobj [, argarray])

Parameters
Thisobj
Optional. Will be used as the object of the current object.

Argarray
Optional. Array of parameters that will be passed to the function.

Description
If argarray is not a valid array or an arguments object, a typeerror occurs.

If neither argarray nor thisobj is provided, the global object will be used as thisobj and cannot be passed with any parameters.

From the official introduction above, we can see that the functions of call and apply are exactly the same, but the parameter transmission method is different. Call separates parameters, apply is to make all parameters into an array for transmission.
