uncaught EvalError Identifier my_function cannot be declared with var in current evaluation scope consider trying let instead

This error occurs when you try to declare a function with the keyword "var" in the current evaluation scope. In JavaScript, functions can be declared using the "function" keyword or by assigning a function expression to a variable using "let" or "const".

To fix this error, you should declare the function using the "function" keyword or assign it to a variable using "let" or "const". For example:

// Using function keyword function myFunction() { // function body }

// Using let keyword let myFunction = function() { // function body }
