How Can I Identify the Calling Function in JavaScript?

How do you find out the caller function in JavaScript?

The JavaScript Function.caller property can be used to access the function that called the current function, providing insight into the call stack.

In the provided example:

function main() { Hello(); }
function Hello() { /* How do you find out the caller function is 'main'? */ }

To find out the caller function of Hello, use the Hello.caller property:

function Hello() { alert("caller is " + Hello.caller); }

However, note that this solution is now deprecated and its use is discouraged as it is non-standard.

Alternative Approaches:

Unfortunately, there is no fully standard way to obtain the call stack in JavaScript. However, older browsers offered a non-standard method using arguments.callee.caller. This approach is no longer supported in modern browsers.
