For example, say I have a function defined as follows:
function foo() { return "Hello, serialized world!"; } I want to be able to serialize that function and store it using localStorage. How can I go about doing that?

In JavaScript, for example, you can serialize an object to a JSON string by calling the function JSON. stringify() . CSS values are serialized by calling the function CSSStyleDeclaration. getPropertyValue() .
Capturing modules in a JavaScript function Because a module is just a normal JavaScript value, it is possible to serialize it just like any other value.
The serialize() method creates a URL encoded text string by serializing form values. You can select one or more form elements (like input and/or text area), or the form element itself. The serialized values can be used in the URL query string when making an AJAX request.
Then you can simply use JSON. stringify and functions will be serialized as strings. Its generally a not good idea in most cases. There are very few circumstances where you want to do this and even then, there is probably a better way.
Most browsers (Chrome, Safari, Firefox, possibly others) return the definition of functions from the .toString() method:
> function foo() { return 42; } > foo.toString() "function foo() { return 42; }" Just be careful because native functions won't serialize properly. For example:
> alert.toString() "function alert() { [native code] }" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
