How to write jslt to achieve the effect of 【firstNotNull】

[ChengHoHang]

for example，here my jslt input

// objectB and objectC nonNull
{
    "objectA":null,
    "objectB": ...
    "objectC": ...
}

so how to write jslt template to achieve the effect of 【firstNotNull】instead of using if objectA != null else if else if .....

This allows me to call like this

let firstNonNullKey = firstNonNull(.objectA, .objectB, .objectC, .......)

am i missing something? please give some help

The fallback function does exactly what you're asking for.
