Developer.Implement chain for #82

Here is a simple example of how you can implement some of these guidelines in a JavaScript web application:

#!/bin/bash

# Create the JavaScript file
cat > myscript.js << EOF
// My JavaScript Application

// Using DRY principle, let's create a function to make HTTP requests
function makeHTTPRequest(method, url, data) {
    // Return a new promise.
    return new Promise(function(resolve, reject) {
        // Do the usual XHR stuff
        var req = new XMLHttpRequest();
        req.open(method, url);

        req.onload = function() {
            // This is called even on 404 etc, so check the status
            if (req.status == 200) {
                // Resolve the promise with the response text
                resolve(req.response);
            } else {
                // Otherwise reject with the status text
                reject(Error(req.statusText));
            }
        };

        // Handle network errors
        req.onerror = function() {
            reject(Error("Network Error"));
        };

        // Make the request
        req.send(data);
    });
}

// Use the above function for GET request
makeHTTPRequest('GET', 'https://myapi.com/data').then(function(response) {
    // Process the response here
    console.log(response); 
}, function(error) {
    console.error('Error:', error);
});

// Use server-side rendering when possible to conserve client resources
// Also consider using lower resolution images or videos where applicable
// Avoid using full-size images as thumbnails
// Consider using system fonts to avoid additional network load from font downloads
// Upgrade or depreciate legacy code when not running on modern infrastructure
EOF

This bash script will create a JavaScript file named myscript.js with a function makeHTTPRequest that makes HTTP requests. This function takes in three parameters: the HTTP method (GET, POST, etc.), the url to make the request to, and an optional data parameter for sending data along with the request.

The script then uses this function to make a GET request to 'https://myapi.com/data' and logs the response. If there's an error with the request, it logs the error.

Note: This script assumes that you are in a Unix-like environment and that you have write permissions to the current directory. If not, you may need to modify it to suit your needs.
