How to get currently running function name using JavaScript ? Last Updated : 17 Dec, 2019 Improve Improve Like Article Like Save Share Report Given a function and the task is to get the name of function that is currently running using JavaScript. Approach 1: Using arguments.callee method: It refers to the currently executing function inside the function body of that function. In this method, we use arguments.callee to refer to the name of the function. So we define a new variable as arguments.callee.toString(). Then we use (variable_name).substr to get the function and then we display it as an alert. Syntax: arguments.callee.toString() You may have to parse the name though, as it will probably include some extra junk.
