#A brief intro into Stateless functions#

So stateless functions are new in React 0.14 which are quite interesting. They look a bit like this.

const Test = ({name, amount}) => {
  return <div className="test">{name} has £{amount}</div>;

ReactDOM.render(<Test name="ben" amount="-2000" />) //  <div className="test">ben has £-200</div>

What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.


Box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
  • elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
  • elem.getClientRects(), elem.getBoundingClientRect()

Put the awesome redux-devtools in it's own window so it doesn't obscure or be obscured by your application
View redux-devtools-separate-window.js
// give it a name so it reuses the same window
var win =, "redux-devtools", "menubar=no,location=no,resizable=yes,scrollbars=no,status=no");
// reload in case it's reusing the same window with the old content
// wait a little bit for it to reload, then render

* VH and VW units can cause issues on iOS devices:
* To overcome this, create media queries that target the width, height, and orientation of iOS devices.
* It isn't optimal, but there is really no other way to solve the problem. In this example, I am fixing

This is a little bash/zsh function to reduce that to `server 8888`. Simply add this to `bash_profile` or `zshconfig`. For more on the P…
