The name property returns the name of the function.
Example
name Syntax
The syntax of the name property is:
func.name
Here, func is a function.
name Parameters
The name property does not take any parameters.
name Return Value
The name property returns the function's name as specified when it was created.
Note: If the function is created anonymously, the length property returns anonymous or ''.
Example 1: Using name Property
Output:
message
In the above program, we have defined a function named message(). We are using the name property to find out the name of the function that we have defined.
Using name as message.name returns the name of the function message() i.e. message.
Example 2: name Property for Anonymous Function
Anonymous function is a function that is created without a name.
We declare anonymous functions without using an identifier. We can create an anonymous function with new Function(..) or Function(..) syntax.
Using the name property in an anonymous function returns anonymous keyword. For example:
Output
anonymous result
In the above program, we have assigned an anonymous function to a variable named result.
The function is inferred as the variable name. So, using name in result returns the variable name- "result".
Example 3: Using name Property in a Variable
Output
func
Here, we have assigned the value of func() to a variable named result. So result.name returns the name of the func() function i.e. func.
