What are the parameters of a JavaScript function?The parameters, in a function call, are the function's arguments. JavaScript arguments are passed by value : The function only gets to know the values, not the argument's locations. If a function changes an argument's value, it does not change the parameter's original value.
What is the difference between Rest parameters and spread parameters?Rest parameters are used to create functions that accept any number of arguments. The spread syntax is used to pass an array to functions that normally require a list of many arguments. Together they help to travel between a list and an array of parameters with ease.
