Different types of function – JavaScript Series – Part 18

In last two part we declare the function in a same style, but there is a another way declare a variable. We are going to learn it today.

Up until now we wrote the functions declaration. Now we are going to learn about function expression.

Here we don’t have a name for the function. So it also called anonymous function.

Let’s write one to understand more about it.

function() {
  console.log('How you doin ?')
Enter fullscreen mode Exit fullscreen mode

this will be function and we’ll store it on a variable and then we’ll call the function using variable()

Example –

Alt Text

This exactly does the same thing as our old function. This pattern is widely use in js, so it is better to know both.

Let’s have a look on the both type

Alt Text

Result –

Alt Text
