So I have an Immutable js Record:

{

 title: "item 1",

 title2: "item 2",

 title3: "item 3"

}

I want to update the keys, so it will become:

{

  new title: "item 1",

  title2: "item 2",

  title3: "item 3"

}

You can use delete keyword, to delete a particular key and then use Object.assign to append it as below:

let hello1={ title: "item 1", title2: "item 2", title3: "item 3"};	



delete hello1['title'];



console.log(Object.assign({'new title': "item 1"}, hello1));
