How does ramda.join work?

ramda.join is a function that concatenates a list of strings into a single string with a specified separator in between each string. It takes two arguments, the separator and the list of strings, and returns the concatenated string. Internally, it uses the Array.join method to concatenate the strings with the specified separator.

const R = require("ramda");

const array = [1, 2, 3, 4, 5];
const separator = " - ";

const result = R.join(separator, array);

console.log(result); // Output: 1 - 2 - 3 - 4 - 5

In this example, ramda.join is used to concatenate the elements of an array with a separator in between. The function takes two arguments: the separator and the array of elements to join. In this case, the separator is ' - ' and the array is [1, 2, 3, 4, 5]. The resulting string, '1 - 2 - 3 - 4 - 5', is then logged to the console.
