Transfer and reference of function parameters in Javascript

Conclusion: Numbers and strings are transmitted to function parameters. Changes in function parameters do not affect external variables. For arrays and objects, the value of the variable of the object (array) is passed to the function parameter. This variable is saved to the address of the object (array. When the function changes the content of the object (array) pointed to by this address, it also changes the content of the object (array) pointed to by the function external variable; when a fun
