abstract operator fun set(propertyName: String, value: Any?) (source)

Platform and version requirements: JS

Calls of the function will be translated to an assignment of value to the receiver indexed (with square brackets/index operation) with propertyName.

E.g. for the following code:

fun test(j: Json, p: String, newValue: Any) {
    j["prop"] = 1
    j.set(p, newValue)

will be generated:

function test(j, p, newValue) {
    j["prop"] = 1;
    j[p] = newValue;
