How to add to a dynamic property?

[steep vessel]

help, please.

this is what I was trying to do

world.afterEvents.playerSpawn.subscribe((data) => {
    const { initialSpawn, player: source } = data;
    let player = data.player;
    let amount = 0

    if (initialSpawn) {

}

    amount++

    world.setDynamicProperty("players_unique", amount);

    const D = world.getDynamicProperty("players_unique");
    console.warn(D);
});```

anddd it didn't work

Is this what you are looking for?: ```js
world.afterEvents.playerSpawn.subscribe((data) => {
const { initialSpawn, player: source } = data;

if (!initialSpawn || source.hasTag('joined')) return; //If it's the first time the player has joined since the server started stop any code below. This will work reguarless of if the player joined already.
source.addTag('joined');
const D = world.getDynamicProperty("players_unique");

world.setDynamicProperty("players_unique", D + 1);

console.warn(D);

});

To add color to code use this:
```js

```

Three back ticks

[steep vessel]

import { world, system } from "@minecraft/server"

world.afterEvents.playerSpawn.subscribe((data) => {
    const { initialSpawn, player: source } = data;
    let player = data.player;
    let amount = 0

    if (initialSpawn) {

}

    amount++

    world.setDynamicProperty("players_unique", amount);

    const D = world.getDynamicProperty("players_unique");
    console.warn(D);
});
