How does ramda.mergeAll work?

ramda.mergeAll is a higher-order function in the Ramda library that takes an array of objects and merges them into a single object by combining their properties. Here is how it works:

First, you need to have the Ramda library installed in your project. This can be done using a package manager like npm or yarn.
Once you have Ramda installed, you can import the ramda module in your code and use the ramda.mergeAll function to merge an array of objects.
The ramda.mergeAll function takes an array of objects as its argument. It merges the objects by copying all the properties of each object to a new object, starting with an empty object.
When there are properties with the same name in multiple objects, the value from the last object in the array will overwrite any previous values. If you want to keep all values for a given property, you can use ramda.mergeDeepRight instead.
The ramda.mergeAll function returns the merged object.

Here is an example of using ramda.mergeAll to merge multiple objects into a single object:

javascript
const R = require('ramda');

// Define some objects to merge
const obj1 = { name: 'Alice', age: 30 };
const obj2 = { city: 'New York', state: 'NY' };
const obj3 = { hobby: 'reading' };

// Merge the objects using mergeAll
const mergedObj = R.mergeAll([obj1, obj2, obj3]);

console.log(mergedObj);
// Output: { name: 'Alice', age: 30, city: 'New York', state: 'NY', hobby: 'reading' }

In this example, we have defined three objects obj1, obj2, and obj3. We then use ramda.mergeAll to merge these objects into a single object mergedObj.

The resulting object contains all properties from the original objects, with properties from the last object in the array taking precedence over properties with the same name in earlier objects.

Note that in a real-world application, you would typically use ramda.mergeAll to combine multiple objects with related properties into a single object, and handle edge cases and conflicts when merging properties from different objects.

const R = require("ramda");

// Define some objects to merge
const obj1 = { name: "Alice", age: 30, city: "San Francisco" };
const obj2 = { name: "Bob", age: 25 };
const obj3 = { city: "New York", state: "NY" };

// Merge the objects using mergeAll
const mergedObj = R.mergeAll([obj1, obj2, obj3]);

console.log(mergedObj);
// Output: { name: 'Bob', age: 25, city: 'New York', state: 'NY' }

In this example, we have three objects obj1, obj2, and obj3, with some overlapping properties. We then use ramda.mergeAll to merge these objects into a single object mergedObj. The resulting object contains all properties from the original objects, with properties from the last object in the array taking precedence over properties with the same name in earlier objects. In this case, the name property from obj2 overwrites the name property from obj1, and the city property from obj3 overwrites the city property from obj1. Note that ramda.mergeAll is a very useful function when dealing with configuration objects that have default values, as it allows you to merge multiple configuration objects into a single object that has all the properties needed to configure your application.
