Debugging Data Contexts in Meteor
Alternatively, if you need to find out more about the data context of a specific template fragment, you can also write a dedicated {{log}} helper:
Template.profile.helpers({
log: function () {
console.log(this);
}
});
And use it directly in your templates:
<template name="profile">

Go: Newton's method for square root
/*
A Tour of Go: page 44
http://tour.golang.org/#44
Exercise: Loops and Functions
As a simple way to play with functions and loops, implement the square root function using Newton's method.
In this case, Newton's method is to approximate Sqrt(x) by picking a starting point z and then repeating: z - (z*z - x) / (2 * z)
