How does ramda.split work?

ramda.split is a function in the Ramda library that takes a separator as a string or a regular expression and a string, and returns an array of substrings by splitting the original string based on the separator. Internally, the split function uses the String.prototype.split() method to split the string and create an array of substrings. If a regular expression is provided as the separator, the function uses RegExp.prototype.exec() method to split the string.

const R = require("ramda");

const str = "hello world";
const splitStr = R.split(" ", str);
console.log(splitStr); // Output: ['hello', 'world']

In this example, ramda.split is used to split a string into an array of substrings based on a delimiter (in this case, a space). The splitStr variable is assigned an array containing the substrings hello and world.
