I create functions in Javascript dynamically. Sometimes I need to check if a certain function is actually already created.

I have the name of the function as a string. How can I check whether a function exists based on a given value in a string?

You can check whether it's defined in the global scope using;

if (typeof window[strOfFunction] === function) {

    // celebrate

    //window[strOfFunction](); //To call the function dynamically!

}
