Lambda Functions

The function with no name.

If you have tried to understand and debug any JavaScript you would have come across the Anonymous function.

Check out the W3C Schools pages for a full explanation of the syntax and usage of these functions. What I have tried to do here is to show a couple of examples that are used on my web pages.

Below is s "Declared Function":

<script>
var x = myFunction(4, 3);
document.getElementById("demo").innerHTML = x;

function myFunction(a, b) {
return a * b;
}
</script>

The declared function has the name "myFunction". In this case the script executes when the page is loaded.

This is the code that I have on my general page about Javascript Functions. All the function does is to multiply 3 by 4.

and then an Anonymous Function:

<script>document.getElementById("lorem").addEventListener("click", function()
{ location.href = "clickable_text.html" })
;</script>

What Wikipedia page says:

" In computer programming, an anonymous function (function literal, lambda abstraction, or lambda expression) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions, or used for constructing the result of a higher-order function that needs to return a function. If the function is only used once, or a limited number of times, an anonymous function may be syntactically lighter than using a named function. Anonymous functions are ubiquitous in functional programming languages and other languages with first-class functions, where they fulfill the same role for the function type as literals do for other data types.
