I am trying to remove an array object using the traditional method: delete subDirectories[index]. However, after deleting, the object changes to [empty]. I have tried filtering for undefined, bool, and NaN, but nothing seems to work. This issue is within a Vue.js project that involves a Vuex action. Any help would be greatly appreciated.
To eliminate any null, undefined, or other false-like values from an array, you can use the following code snippet:
var arr = [1, 3, 5, null, False];
var res = arr.filter(val => val);
console.log(res); // [1, 3, 5]
Alternatively, you can specifically exclude null and undefined values:
var res = arr.filter(val => (val !== undefined) && (val !== null));
console.log(res); // [1, 3, 5]
