can be a variable, or even an expression. The switch statement uses the strict equality operator when comparing values, so type conversions do not occur. Any function can implement the return value at any time by the return statement followed by the value to be returned, and any code after the return statement will never be executed. Strict mode has some limitations on functions: The function cannot be named eval or arguments;The parameter cannot be named eval or arguments;Two name

As an exercise, you can try to modify the function of calculating the factorial yourself.

() method to get a list of tuples that contain key and value pairs. Because the dictionary itself is hashed, it is unordered. A hash table generally has good performance because it is fairly fast to query with keys.The syntax format for a dictionary entry is the key: value. Also, multiple dictionary entries are included in the ({}). To create a dictionary, you only need to assign a dictionary to a variable, regardless of whether the dictionary contains elements.From the
