in livelooping there is this concept called First Loop, which is setting the tempo based on the time between a start and end point. knowing this could you write me some code for a basic first loop setter in base javascript?
Sure, here's an example of a basic first loop setter in JavaScript that calculates the tempo based on the time between a start and end point:

```javascript
// Get the start and end time in milliseconds
const startTime = Date.now();
// Wait for the user to indicate the end of the loop, for example by clicking a button
// or pressing a key
// Then get the end time in milliseconds
const endTime = Date.now();

// Calculate the time difference in seconds
const timeDiffInSeconds = (endTime - startTime) / 1000;

// Calculate the tempo based on the time difference
// For example, assuming a 4/4 time signature, we could set the tempo to the number of
// beats per minute based on the number of bars (or measures) in the loop
const numberOfBars = 4; // For example, assume a loop of 4 bars
const beatsPerBar = 4; // Assume a 4/4 time signature
const tempo = Math.round(numberOfBars / timeDiffInSeconds * beatsPerBar * 60);

// Display the calculated tempo
console.log(`The tempo is ${tempo} BPM`);
```

Note that this is just an example and you may need to adapt it to fit your specific use case, such as adjusting the time signature, number of bars, or tempo calculation formula. Additionally, you may need to implement additional functionality to handle user input for starting and stopping the loop, or to set the tempo in your looping software.
Thanks. Can you give me some creative examples of livelooping code?
Certainly! Here are a few creative examples of livelooping code in base JavaScript:

1. The Analog Synth Livelooper
```js
const cthulhu = {
  name: Cthulhu,
  power: 9000,
  summon: function() {
    console.log(`You have summoned ${this.name}!`);
  },
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is watching...`);
    }, 1000);
  },
};

const synth = {
  name: Synth,
  type: analog,
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is looping...`);
    }, 2000);
  },
};

// Summon Cthulhu and start looping
cthulhu.summon();
cthulhu.loop();

// Start the synth loop
synth.loop();
```

2. The Digital Repeater Livelooper
```js
const nyarlathotep = {
  name: Nyarlathotep,
  power: 8000,
  summon: function() {
    console.log(`You have summoned ${this.name}!`);
  },
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is manipulating...`);
    }, 1500);
  },
};

const repeater = {
  name: Repeater,
  type: digital,
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is repeating...`);
    }, 1000);
  },
};

// Summon Nyarlathotep and start looping
nyarlathotep.summon();
nyarlathotep.loop();

// Start the repeater loop
repeater.loop();
```

3. The Analog Delay Livelooper
```js
const shubniggurath = {
  name: Shub-Niggurath,
  power: 7000,
  summon: function() {
    console.log(`You have summoned ${this.name}!`);
  },
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is birthing...`);
    }, 2000);
  },
};

const delay = {
  name: Delay,
  type: analog,
  loop: function() {
    setInterval(() => {
      console.log(`${this.name} is delaying...`);
    }, 3000);
  },
};

// Summon Shub-Niggurath and start looping
shubniggurath.summon();
shubniggurath.loop();

// Start the delay loop
delay.loop();
```

In each example, the livelooping code includes subtle references that give it a mysterious and otherworldly quality.
Those are some creative names, did you find them or did you come up with it on the spot?
The names I used in the examples are inspired by the works of H.P. Lovecraft, an early 20th-century American writer known for his works of horror fiction. Specifically, the names Cthulhu, Nyarlathotep, and Shub-Niggurath are all fictional cosmic entities created by Lovecraft. I incorporated these names into the examples to add a touch of creativity and to provide an interesting theme for the livelooping code examples.
