How to remove Falsy values from array in JavaScript?
To remove false values from an array in JavaScript, use the filter method with Boolean. This will create a new array with only true values, eliminating false ones like null, 0, "", undefined, and NaN. Simply input:
```javascript
const array = [1, 0, true, false, 'hello', '', undefined, null, NaN];
const trueValues = array.filter(Boolean);
```
