Method 1: .entries () We can use Object.entries () to convert a JSON array to an iterable array of keys and values. Object.entries (obj) will return an iterable multidimensional array. We can use this output to find our keys and values in a bunch of different ways. The Object.entries() method returns an array of a given object's own enumerable string-keyed property [key, value] pairs. This is the same as iterating with a for...in loop, except that a for...in loop enumerates properties in the prototype chain as well. Since Kotlin is 100% interoperable with Java, the majority of Java libraries are compatible with Kotlin, and RxJava is no exception! You could use RxJava and RxKotlin in your project, but to help keep things simple, I'll be sticking to RxJava throughout this tutorial. "/> Kotlin iterate through json object
