You can use the `parseFloat()` method to remove trailing zeros from a number in JavaScript. The `parseFloat()` method [parses a string](https://attacomsian.com/blog/convert-string-to-number-in-javascript#parsefloat-method) into a floating point number while removing all the trailing zeros.

```javascript
const num = 3.50000
const res1 = parseFloat(num)
console.log(res1) // 3.5

// parse the string back to a number
const str = '6.870000'
const res2 = parseFloat(str)
console.log(res2) // 6.87
```

The `parseFloat()` method parses the given string and returns a floating point number without trailing zeros.

If you need to set a specific number of decimal places, use the `toFixed()` method. The `toFixed()` method returns a string representation of the number with the specified decimals.

```javascript
const num = 2.347000
const res = parseFloat(num.toFixed(2))
console.log(res) // 2.35
```

As you can see above, the `toFixed()` method rounds the number if required and pads the fractional part with zeros if the specified decimal places are more than the number has.
