Determine whether a specific function is called or run during the execution of a Javascript program

Trying to determine if a specific function is being run at runtime in JavaScript, especially when the function is part of a direct package dependency on either a production or development server. Is there a way to do this dynamically?

Answer №1

To monitor access for code that is within your control and can be updated, you have the option to track it by setting up 'getters' for the method's context:

const history = [];
const toolKit = {
  get division(){
    history.push(`division accessed: ${Date()}`)
    return (numA, numB) => numA / numB;
  }
};

const output = toolKit.division(10,2);

console.log(output);
console.log(history);
