Hands-On Data Structures and Algorithms with JavaScript

Brute-force Fibonacci generator

Let's take a Fibonacci generator, for example, and brute-force the generation of some numbers:

var _ = require('lodash');var count = 10;bruteForceFibonacci(count);function bruteForceFibonacci(count) {   var prev = 0;   var next = 1;   var res = '';   res += prev;   res += ',' + next;   _.times(count, ()=> {      var tmp = next;      next = prev + next;      prev = tmp;      res += ',' + next;   });   console.log(res);}

Here, we can see that we are not applying any domain knowledge; we simply take the two previous numbers from the series and add them. This is a fine way of doing it, but we can see that there are some improvements to be made here.
