NEW QUESTION # 119
A developer needs the function personalizeWebsiteContent to run when the webpage is fully loaded (HTML and all external resources).
Which implementation should be used?
Answer: A
Explanation:
________________________________________
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge JavaScript defines two main page-loading events:
DOMContentLoaded
Fires when the HTML document has been completely parsed.
External resources like images, stylesheets, iframe contents, etc. may not be loaded yet.
load event on window
Fires when:
HTML is fully parsed
All dependent resources (images, scripts, CSS, fonts, etc.) are fully loaded The requirement states:
"when the webpage is fully loaded (HTML content and all related files)" This aligns exactly with the window load event.
Implementation:
window.addEventListener("load", personalizeWebsiteContent);
This matches option B.
________________________________________
JavaScript knowledge references (text-only)
DOMContentLoaded fires after HTML parsing only.
load fires after all page resources finish loading.
The window object is the correct target for listening to the full load event.

NEW QUESTION # 121
A Node.js server library uses events and callbacks. The developer wants to log any issues the server has at boot time.
Which code logs an error with an event?
Answer: B
Explanation:
console.log('ERROR', error);
}
Explanation:
Node.js event-based modules use the EventEmitter pattern.
The correct syntax for listening to events is:
emitter.on('eventName', callback)
The server library emits an 'error' event, which must be listened to using .on.
Option analysis:
A: .catch is for Promises, not EventEmitters.
B: .error is not an EventEmitter method.
C: Correct. Listens to the 'error' event.
D: try...catch only captures synchronous errors, not event-based asynchronous errors.
Therefore, the correct answer is option C.
JavaScript Knowledge Reference (text-only)
The EventEmitter API uses on(event, handler) to listen for events.
Errors emitted asynchronously cannot be caught with try...catch.
The 'error' event is standard for Node.js modules to signal operational errors.

Teams at Universal Containers use this module in a number of projects. A particular project has thepackage, json definition below.
A developer runs this command: npm install. Which version of bar .awesome is installed?
Answer: A
NEW QUESTION # 123
A developer initiates a server with the file server.js and adds dependencies in the source code's package.json that are required to run the server.
Which command should the developer run to start the server locally?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From JavaScript/Node.js Knowledge:
In a Node.js project that uses package.json, you typically define a "start" script:
{
"scripts": {
"start": "node server.js"
}
}
Then you start the app with:
npm start
npm start:
Looks up the "start" script in package.json.
Runs the command defined there (commonly node server.js).
This is the standard way to start a Node.js app with npm-managed dependencies.
Why others are incorrect:
A . node start
Tries to run a file named start with Node; does not use package.json scripts.
C . npm start server.js
npm start does not take the script filename as an argument in this way; it just runs the start script as defined.
D . start server.js
Not an npm or node command; on some shells it just tries to "start" a process but is not the standard Node/npm workflow.
Relevant concepts: package.json, npm scripts, npm start, Node entry file execution.
