Still Within · Compassionate guidance on the path of the heart
In my life, I have recognized immense benefit by consciously extending myself beyond what is comfortable.By choosing to encounter all that within me is unknown—fear, grief, and death; silence, ecstasy, and unity—I have uncovered a peace inside myself that seems to deepen my capacity to be with all the uncertainties of what it means to be human. Feeding this inquiry has allowed me to meet suffering

Multiple return values in ECMAScript 6
If you combine the features “property value shorthand†and “destructuringâ€, ECMAScript 6 gives you an elegant way to handle multiple return values. This blog post explains why that is useful and how it works. Destructuring  # Destructuring is an ECMAScript 6 feature which lets you use patterns to extract values from an object: let obj = { first: 'Jane', last: 'Doe' }; let { first: f, last: l } = o

The ECMAScript 6 schedule changes
Allen Wirfs-Brock, editor of the ECMAScript 6 specification, recently mentioned on Twitter that the schedule for ECMAScript 6 has changed slightly. The changes  # This is the content of Wirfs-Brock’s tweets: TC39 has decided to move the formal publication date of the ECMAScript 6 standard to June 2015. Work for ECMAScript 7 continues on schedule. The extra time is for more implementation feedback
ECMAScript 6’s new array methods
Check out my book (free online): “Exploring ES6â€. Updated version of this blog post: chapter “New Array featuresâ€. This blog post explains what new array methods ECMAScript 6 will bring and how to use them in current browsers. Note: I’m using the terms constructor and class interchangeably. Class methods  # Array has gained methods of its own. Array.from(arrayLike, mapFunc?, thisArg?)  # Array.fro

Creating defensive objects with ES6 proxies - Human Who Codes
Posted at April 22, 2014 by Nicholas C. Zakas Tags: ECMAScript 6, JavaScript, Proxies This past week I spent an hour debugging an issue that I ultimately tracked down to a silly problem: the property I was referencing didn’t exist on the given object. I had typed request.code and it should have been request.query.code. After sternly lecturing myself for not noticing earlier, a pit formed in my sto
Handling required parameters in ECMAScript 6
In ECMAScript 5, you have a few options for ensuring that a required parameter has been provided, all of which are somewhat brittle and inelegant: function foo(mustBeProvided) { if (arguments.length < 1) throw new Error(...) if (! (0 in arguments)) ... if (mustBeProvided === undefined) ... } In ECMAScript 6, you can (ab)use default parameter values to achieve more concise code (credit: idea by All
