Gets the Unix timestamp from a `Date` object.
|
|
|
|
- Use `Date.prototype.getTime()` to get the timestamp in milliseconds and divide by `1000` to get the timestamp in seconds.
|
|
- Use `Math.floor()` to appropriately round the resulting timestamp to an integer.
|
|
- Omit the argument, `date`, to use the current date.
|
|
|
|
```js
|
|
const getTimestamp = (date = new Date()) => Math.floor(date.getTime() / 1000);
|
|
```
|
|
|
|
```js
|
|
getTimestamp(); // 1602162242
|
|
```
