Insert Data into a Array periodically JS(react native)

Question

I have a simple array which contains objects like the following -

Array:{
  o1:{
    }
  o2:{
    }
  o3:{
    }
  ......
  o100:{
    }
}

So here I have an object -

OBJECT:{

  }

Which I need to insert into the array periodically - like after every 5 items the new object should be inserted.

So how should I insert it into the array? The data in the existing index should not be overwritten.

Anyone can give me a hint?

Thanks.

Answer 1

It depends on the use case but it looks like you want to use the splice [javascript array method]. If you have your complete Array object, you can loop over it with something like this:

const step = 5;
for (var i = step; i < yourArrayObject.length; i += step) {
  yourArrayObject.splice(i, 0, objectToInsert)
}

This will take your completed Array object and insert the object every step places. Be aware that this code will mutate the original Array object.
