How does ramda.converge work?
ramda.converge is a higher-order function that takes a function and a list of functions and returns a new function. The new function takes arguments that are passed to each function in the list and then passes the results of those functions as arguments to the first function.

const greet = (greeting, name) => `${greeting} ${name}!`; const greetWithExcitement = R.converge(greet, [R.toUpper, R.identity]); console.log(greetWithExcitement("hello", "world")); // "HELLO world!"
In this example, R.converge is used to create a new function that takes two arguments: a greeting and a name. The greet function concatenates these two arguments into a string, and the greetWithExcitement function is created by calling R.converge with greet as the first argument, and an array of two functions as the second argument. The first function in the array, R.toUpper, converts the greeting argument to uppercase, while the second function, R.identity, simply returns the name argument. The result is a function that will take two arguments (greeting and name), convert the greeting to uppercase, and then call greet with the two arguments.
