Post a Comment On: A Nod to Nothing

I was right.  The simple math exercise was really, really simple.  Use Vue and it'll lock the format to numeric, has a UI, autoupdates the answers and, with a min and a bit of javascript (validity.valid) enforces 0+, aka no negative numbers, per the exercise challenges.

The Fiddle code... HTML: Javascript + Vue 2.2.1 var app = new Vue({ el: '#app', components: { }, data: { num1: 800, num2: 40 }, computed:{ sum: function(){ return this.num1 + this.num2; }, sub: function(){ return this.num1 - this.num2; }, multi: function(){ return this.num1 * this.num2; }, div: function(){ return this.num1 / this.num2; } } })
