Very small curry function

Curry function

function curry(fn) {
  return (...args) => {
    if (args.length >= fn.length) {
      return fn.apply(null, args)
    }
    
    return function internal(...args1) {
      args = args.concat(args1)
    
      if (args.length >= fn.length) {
        return fn.apply(null, args)
      }  
      
      return internal
    }
  }
}

const curried = curry((a, b, c) => `${a} ${b} ${c}`)

console.log(curried("a", "b", "c")) // "a b c"
console.log(curried("a", "b")("c")) // "a b c"
console.log(curried("a")("b", "c")) // "a b c"
console.log(curried("a")("b")("c")) // "a b c"
