Transforming two child arrays within an object into a single array using Ramda

Question

Transforming two child arrays within an object into a single array using Ramda

I am looking to transform an object into an array. The object I have is structured like this:

const data = {
    t1: [ {"a": 1, "a1": 2}, {"b": 3, "b1": 4}, {"c": 5, "c1": 6} ], 
    t2: [ {"d": 2}, {"e": 2}, {"f": 2} ]
}

The desired output is an array containing all the objects within the arrays of t1 and t2 without any nesting:

[ {"a": 1, "a1": 2}, {"b": 3, "b1": 4}, {"c": 5, "c1": 6} , {"d": 2}, {"e": 2}, {"f": 2}]

To achieve this transformation, I can use the following code:

const join = data.t1.concat(data.t2)

My question is whether there is a similar function available in the Ramda library that can accomplish this task?

Using Array.values and Array.reduce method is a simple solution.

If your browser or node environment supports the Array.flat method, you can opt for that as well.

Here's an example of how you can achieve this:

const mergeArrays = data => Object.values(data).reduce((result, value) => [...result, ...value])
const mergeArrays2 = data => Object.values(data).flat()

const data = {
    t1: [ {"a": 1, "a1": 2}, {"b": 3, "b1": 4}, {"c": 5, "c1": 6} ], 
    t2: [ {"d": 2}, {"e": 2}, {"f": 2} ]
}

console.log(mergeArrays(data))
console.log(mergeArrays2(data))
