I have an array of string (
ObjectIds) in mongoDB.
I want to toggle an element in that array: If that element exists in the array, remove it, otherwise push that element.
arr = ["5b608c0769698c3990c64ef3","5b608c0769698c3990c64ef4"] element = ["5b608c0769698c3990c64ef3"]
arr = ["5b608c0769698c3990c64ef4"]
I am creating a blog website and in the Blog Schema I am storing the id of each user who has liked that blog, so that I can highlight the like button when blog is shown to the user.
