The official name of the JavaScript language is actually "ECMAScript" because the committee that defines the language specification is part of the European Computer Manufacturers Association (ECMA). Generating a sequence is a common programming task. Thatâs where generator functions come in. We will implement a simple algorithm to find the nth Fibonacci number in javascript using three different approaches. As quoted in the previous link, the next number in a Fibonacci sequence is equal to the previous number plus the previous number of the previous number.

In a previous post I discussed , JavaScript Arrays, and made use of Fibonacci.js module to return a Fibonacci sequence of numbers. The Fibonacci sequence is a series of integers, beginning with zero and one, in which each value is the sum of the previous two numbers in the series. x n = x n-1 + x n-2. Posted in Algorithms, Maths | Tagged DP, medium. By making small modification of Math.min(a, b) instruction we are able to find minimal value inside properties of a and b variables. It could be defined via the formula: F(0)=1ï¼F(1)=1, F(n)=F(n-1)+F(n-2) In ES5 In ES6 there is a feature so called âgeneratorFunctionâ which can achieve the calculation of Fibonacci Sequence in a very convenient way.
