I have a array of objects like so:
const attendList = [
{
"first": "John",
"last": "Foo",
"uid": "-Lz8YxIYM_4L3f9nKM70",
},
{
"first": "Jake",
"last": "Foo",
"uid": "-Lz8YxIYM_4L3fsdfM70",
}
...
]
Then I have an array containing the keys
const found = ["-Lz8YxIYM_4L3fsdfM70", "-Lz8YxIYM_4L3fsdf333", "-Lz8YxIYM_r4hfsdf333" ]
I want to sort attendList by placing the items that are in found at the bottom of the list. My incorrect attempt (using lodash) is:
let SetItemsLast = _.sortBy(attendList, ({uid}) => found.includes(uid) ? 0:1);
I'm obviously not doing it correctly. How can I resolve this?
Try this if you need to keep the attendList items in order otherwise.
let SetItemsLast = attendList.sort((a, b)=>{
if(found.includes(a.uid)){
return 1;
}
if(found.includes(b.uid)){
return -1;
}
return 0;
});
If you don't care whether the items at the bottom remain in order, you can just do this.
let SetItemsLast = attendList.sort((a, b)=>{ return found.includes(b.uid) ? -1:0; });
