But the rule does not get out of context, that is the eval context, and the variable does not have the {Dontdelete} attribute.
Copy Code code as follows:

Way one: The most common way to declare by means of numeric literal
var num = 123;
Mode two: The occasional use of the way, most of the time is the string into a number

Mode III: Rarely used, the various gods books, including Rhino books, are included in the Not recommended way

2. Otherwise, an object is returned. For the type of the object to be converted, see the following table. The example above is essentially equivalent to new Number (123 ):
3. Simple Test Cases
The Code is as follows:
Var num = Object (123 );Console. log (typeof num); // output: object console. log (Object. prototype. toString. call (num); // output: [object Number]
