After Editting Javascript Code (HTTP Request) in "Code + Test" Editor and Saving, The Newly Created Code Isn't Running

Question

It's probably obvious, please bear with me. I'm a software development newbie. The only development I've done is VBA script in Excel and PowerFx functions in Power Platform.

I am learning how to make an azure function. Specifically, I am working on making an Azure HTTP request with Javascript code. I copied and pasted this Javascript code I found on the internet:

module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    const name = (req.query.name || (req.body && req.body.name));
    const responseMessage = name
        ? "Hello, " + name + ". Hello there This HTTP triggered function executed successfully."
        : "Hello, This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.";
    context.res = {
        // status: 200, /* Defaults to 200 */
        body: responseMessage
    };
}

When I run this code in the Azure portal, the output is as expected. It says: "Hello, Azure. This HTTP triggered function executed successfully."

So, I decided to start playing around with it. My goal was, instead of the output saying "Hello, Azure. This HTTP triggered function executed successfully."

... I wanted it to say...
"Hello buddy, Azure. This HTTP triggered function executed successfully."

The only difference is I put in the word "buddy".

So, I change the string for the response message by including the word "buddy". My new code is shown below:

module.exports = async function (context, req) {

    context.log('JavaScript HTTP trigger function processed a request.');

    const name = (req.query.name || (req.body && req.body.name));

    const responseMessage = name

        ? "Hello buddy, " + name + ". Hello there This HTTP triggered function executed successfully."

        : "Hello, This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.";

    context.res = {

        // status: 200, /* Defaults to 200 */

        body: responseMessage

    };

}

The only thing that is changing is that one line of code, that now has the word "buddy" in it.

When I click "Run" in the Azure portal, I still get the same message:
"Hello, Azure. This HTTP triggered function executed successfully."

... when I want it to say...

"Hello buddy, Azure. This HTTP triggered function executed successfully."

The weird thing is, I waited a day, and tried it the next day without changing anything. And it worked! So then I tried changing the code even more to say "buddy-ol-pal" instead of "buddy"... but it didn't work.

Any feedback here is appreciated, thank you!!! Below is a screenshot of what I'm seeing on my computer. Where the question mark is, it should say "buddy-ol-pal". I clicked Save, and then the "Refresh" button (next to "Discard" button) before running.

Hey @Noah Masimore - Welcome to Azure Functions, and thanks for making a well-formatted post with great details on the MS Q&A!

The edits you've made in the code were simple string changes and because Javascript is an interpreted language that does not require a compilation process, you should have seen your changes reflected in a matter of less than a minute (or two at max) from hitting Save to hitting Run in the Test/Run blade. As such, the delay that you've observed was not of your doing in any way but possibly an abrupt networking (or browser) issue or a service up-time issue at Azure's end. I hope this doesn't keep you from continuing to play with Functions and the learning journey that you've ventured upon.

While Azure Portal development is a great starting point, I recommend moving on to the next best thing which is the setup of your own local development environment. Here's a doc that may be of help: Code and test Azure Functions locally
