How to Write Global Functions in Postman

Question

I need help writing a common function to use across a collection of requests which will help with building a framework.

I have tried using the below format

Answer 1

Without eval:

Define an object containing your function(s) in the collection's pre-request scripts without using let, var, etc. This attaches it to Postman's global sandbox object.

utils = {
  myFunc: function() {
    return 'hello';
  }
};

Then within your request's pre-request or test script section just call the function:

console.log(utils.myFunc());
