How does ramda.mergeDeepRight work?

ramda.mergeDeepRight is a function that takes two objects as arguments and recursively merges them into a single object, with properties from the second object overwriting properties of the same name in the first object, and nested objects being merged recursively.

const R = require("ramda");

const obj1 = {
  a: {
    b: {
      c: 1,
    },
  },
};

const obj2 = {
  a: {
    b: {
      d: 2,
    },
  },
};

const merged = R.mergeDeepRight(obj1, obj2);

console.log(merged);
// Output: { a: { b: { c: 1, d: 2 } } }

In this example, ramda.mergeDeepRight is used to merge two objects, obj1 and obj2, into a new object called merged. The resulting object merged contains all the properties of both obj1 and obj2, with any conflicts resolved by taking the value from obj2. In this case, the a.b property is an object in both obj1 and obj2, so ramda.mergeDeepRight combines the two objects by merging the properties c and d. The resulting object is { a: { b: { c: 1, d: 2 } } }.
