How does lodash.updateWith work?

lodash.updateWith is a method in the Lodash library that allows you to update the value of a nested property in an object using a customizer function, which is called for each element in the path, and optionally replaces or inserts the value in the object.

const _ = require("lodash");

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

_.updateWith(obj, "a.b.c", (val) => val * 2);

console.log(obj.a.b.c); // Output: 2

In this example, lodash.updateWith is used to update the value of c in the nested object obj.a.b by doubling its value. The function takes in the object to update as the first argument, the key to update as the second argument, and a customizer function as the third argument. The customizer function is invoked with the new value of c and returns the updated value. In this case, the customizer function simply doubles the value of c.
