Concat string with GROQ

{
 firstName: "A",
 lastName: "B",
 fullName: firstName + lastName
}

// output: fullName: A B 
However, if one of the value is null, the output is null

{
 firstName: NULL,
 lastName: "B",
 fullName: firstName + lastName
}

//output: NULL
Expected: output: B
How should I check the Null value?

Perhaps you can try using
coalesce
function ?
coalesce(firstname, lastname)

Maybe try using
coalesce()
function ?
'fullName': coalesce(firstName, "") + coalesce(lastName,"")
