Javascript Remove [] from array?

Question

I have the following array

 [Array(1), Array(1), Array(0)]

Here is the formatted version

[{…}]
[{…}]
[]

How can I remove [] ?

Can you give more details on it., Is that mean, you want to remove empty arrays? — Rafee

So you have an array of arrays & you want to remove the empty array?

You can filter out the values you don't want by using .filter

E.g

const arr = [ [], ['1', '2'], ['3', '4'] ].filter(v => v.length > 0);

update your sample as const arr = [ [], ['1', '2'], ['3', '4'] ].filter(v => v.length > 0);

Try to use filter, this will iterate through the your array and will return array item which are having length greater than 0

result = obj.filter(x=> x.length > 0)

You can check the length of your internal array to determine whether you should keep the value when you filter the array.

const arr = [Array(1), Array(1), Array(0)]

console.log(
  arr.filter(x => x && x.length)
)
