Function Object Javascript

Function Object Javascript Share / Like

The Javascript Function object is associated with any function in Javascript regardless if it uses the "new" syntax to explicitly target the Function constructor or not. It is best to NOT use the "new Function" constructor unless your script requires it to dynamically create executable code in the current scope of your script.

We will demonstrate one after the other so you can see the contrast when using the "new Function" syntax to use the Function constructor.

Javascript CODE EXAMPLE

var findAverage = new Function("a","b","c","return (a + b + c) / 3");
document.write(findAverage(4,7,9));

Javascript CODE EXAMPLE

function findAverage(a,b,c){ return (a + b + c) / 3; }
document.write(findAverage(4,7,9));

Here is a more information about scripting Javascript Functions in our Javascript Building Blocks section. We detail function logic much more on that page.
