An example is shown below that will make us understand how to use an anonymous and why it is different from a normal function:
The above code is the implementation of the anonymous function where:
The main focused point is that there is no function we have declared before. It is just the keyword function and parenthesis. In the case of a normal function, we use to name the function as shown in the below code example:
Here, we have created a normale () function, which is a normal function. It is the difference between an anonymous function and a normal function.
Finally, we have invoked the created function.
So, in this way the basic implementation of an anonymous function is done.
The above code implements the use of anonymous function as an argument to a new function where:
It is one such implementation and use of the anonymous function.
Immediate execution of a function
In order to invoke and execute a function immediately after its declaration, creating an anonymous function is the best way. Let' see an example to understand how we can do so:
In the above code, the anonymous function is invoked immediately where it works as described in the following way:
The first step is to define the function expression, as shown below:
After defining the function, we can see the trailing parenthesis () followed by the terminator (;) that are used for invoking the defined function as shown below:
In this way, the anonymous function can be invoked immediately.
Note: One can also pass the arguments in the function and invoke it too.
These are some uses of an anonymous function that concludes that an anonymous function is the one with no name, can be invoked immediately and can be used as an argument value in a normal function definition.
