Replace a single key in a json object
Hi All,
I want to replace just one keyname with another name. For example:
initial input :
{
“Field1”: “bar”,
“Field2”: “bar”
}
desired output :
{
“NEWNAME”: “bar”,
“Field2”: “bar...
Forum Discussion
$.mapKeys((value, key) => key == ‘Field1’ ? ‘NEWNAME’ : key) has worked fine for me.
Also the approach I was using already is the 2 mapper approach you have suggested. One mapper for copying and second to delete. But I thought if we use this $.mapKeys approach, we can do this with one mapper right. Thats why was thinking of the $.mapKeys approach.
Anyway Thanks a lot for that!! 🙂 🙂
You should only need a single mapper in either approach. The delete transformations are done last. So, you can combine the copy and delete transformations into a single mapper.
