Two-way data binding (Angular) vs one-way data flow (React/Flux)
<p>In the last week, I’ve been trying to make sense how <a href="https://docs.angularjs.org/guide/databinding" rel="noreferrer">two-way data binding (Angular)</a> and <a href="https://youtu.be/i__969noyAM" rel="noreferrer">one-way data flow (React/Flux)</a> are different. They say that <strong>one-way data flow is more powerful and easier to understand and follow</strong>: it is deterministic and helps avoiding side-effects. In my newbie eyes though, they both look pretty much the same: <strong>the view listens to the model, and the model reacts on actions done to the view.</strong> Both claim that the model is the <em>single source of truth</em>.</p>

<p>Could anybody comprehensively explain in understandable way how they are <em>really</em> different and how one-way data flow is more beneficial and easier to reason about?</p>
