Returning implicit vs explicit Promises from async functions?

Implicit Promise return
async function f() {
return 1;
}
Explicit Promise return
async function f() {
return Promise.resolve(1);
}

[A]

const waitAndPrint = async (message, seconds) => {
await new Promise((resolve) => setTimeout(resolve, seconds * 1000));
console.log(message);
};
waitAndPrint("First call!", 3);
waitAndPrint("Second call!", 2);
waitAndPrint("Third call!", 1);

Correct Output:
Third call!
Second call!
First call!

[B]

const waitAndPrint = async (message, seconds) => {
await setTimeout(() => {}, seconds * 1000);
console.log(message);
};
`waitAndPrint("First c

async function declaration to async arrow function

async function declaration:

async function foo() {

// await fetch('some-url');

}

​

async arrow function (method #1):

const foo = async () => {

// await fetch('some-url');

};

​

async arrow function (method #2):

async const foo = () => {

// await fetch('some-url');

};

​

What are the pros and cons between method #1 and method #2?

Generally new to Logging, Alerting, and Monitoring. I've been tasked with setting up Splunk logs.

Background: Project is about a year old, so it's relatively young from my perspective. The initial configuration was already set up and we had some logs but very minimal stuff. As the project grew the logging was not kept up. Our application is a typical dashboard where users can log in and access the products my company offers and they've purchased a licenses for.

​

Questions:

  • Looking for any input or suggestions as to what events I should be logging. Already have the general log in and log out flows covered as well as forgot password and the most common routes.
  • Other than looking at the interesting fields in a search result, how else can I explore what data I have ava

What should the average time to complete CodeWars katas be based on the rank?

As the title states, I'd like to get this subreddit's input on a what the average time should be to complete CodeWars katas based on their rank?

For example, I'm at a point where I can solve 4 kyu katas, although I tend to take around 35-50 minutes to solve them. In my opinion, if this was a technical interview this is way too long. So although I feel encouraged because I can solve these type of problems now, it feels like fool's gold.

[USA Ca/Tx] First time buyer, please help me ground my expectations before I waste other people's time.

First off with the background details.. I'm interested in purchasing a 2016 Lexus NX200t F Sport with under 60K miles. Using the popular websites to look for cars, I see a good number of cars available within the prices range $22,966 - $24,993. I'm using the nationwide/all miles filter to get a better "feel" of the true price. I spend time in Southern California and Texas, so I can buy the car in either state (I won't try to get a dealer to match price from a diff dealer 500 miles away). In terms of finance, I'm can put $7500 in downpayment. I will try to finance through a credit union and inform the dealer that if they can beat the rate I have been offered I will go through them, same money

[Help/Clarification] Single .container div versus several .container divs

Noob question here, assuming I'm creating a simple product landing page with 3 sections: Features, How It Works, and Pricing. Which of the following code structures would be best, and why? Thanks to everyone in advanced.

<div class="container">
    <div class="row" id="features">
        <div class="col">
        </div>
