  • You can apply CSS to your Pen from any stylesheet on the web.
  • Just put a URL to it here and we’ll apply it, in the order you have them, before the CSS in the Pen itself.
  • If the stylesheet you link to has the file extension of a preprocessor, we’ll attempt to process it before applying.
  • You can also link to another Pen here, and we’ll pull the CSS from that Pen and include it.
  • If it’s using a matching preprocessor, we’ll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

Understanding The React Source Code — Initial Rendering (Simple Component) I

  • var childrenLength = arguments.length — 2; if (childrenLength === 1) { props.children = children; // scr: one child is stored as object } else if (childrenLength 1) { var childArray = Array(childrenLength); for (var i = 0; i childrenLength; i++) { childArray[i] = arguments[i + 2]; // scr: multiple children…
  • …var ReactElement = function(type, key, ref, self, source, owner, props) { // This tag allow us to uniquely identify this as a React Element $$typeof: REACT_ELEMENT_TYPE,// Built-in properties that belong on the element type: // scr: ————– ‘h1’ key: // scr: ————– not of interest for now ref: // scr:…
  • The name TopLevelWrapper explains what it does — wrap the top level element (of the component tree passed through render()):An important definition here is that of TopLevelWrapper, I type three stars here *** for you to CTL-f, as you might need to come back to this definition later:…var TopLevelWrapper = function() {…
  • The only line that is effective before the logic processes to next step is… var nextWrappedElement = { child: nextElement, that it should be easy to see how the target object of this step is constructed with React.createElement, the function we just examined in the last a `ReactCompositeComponent` using `ReactElement[2]`The…
  • In our context, it checks the ReactElement[2]’s type (i.e., TopLevelWrapper) and creates a ReactCompositeComponent accordingly.function shouldHaveDebugID) { var instance;… } else if (typeof node === ‘object’) { var element = node; var type = element.type;… // Special case string values if (typeof element.type === ‘string’) {… } else if {……

UI updating, in its essential, is data change. React offers a straightforward and intuitive way to program front-end Apps as all the moving parts are converged in the form of states. Code review of…

5 practical tips to finally learn React in 2018

  • I’ve learned React (as many other things) the hard way: I got my feet wet, experimented a lot, read a lot, sometimes spent weeks without much progress while other times I could have had a dozen a-ha moments in a single evening.
  • Bear in mind that this advice relates to learning React fundamentals.
  • Instead, these are just some helpful guidelines to help you learn React fundamentals faster — so you can move on to the other things.
  • It’s not perfect — one page at a time with no way to switch — but it lets you get started fast.
  • Storing the current page name in a local variable is not ideal as we can’t change it… so we can store it in the state instead: – – And since might want to go to , we can pass each page a function to switch to another page: – -…

Your job needs you to learn React yesterday… You’ve never even read about it until 3 days ago. Sounds ike you? Here are some tips to learn faster.

Using Bootstrap With create-react-app

  • From your project folder, enter the following: – – Now the Bootstrap files will be located in your folder.
  • This is where we will put our bootstrap source files.
  • You will need to have the installed globally, so from your command line enter: – – You will also need grunt and other libraries install locally into your project, so enter the following from your project folder – – In order to import your bootstrap files, you need to create…
  • From our command line inside of our project folder we can now enter to compile our LESS files one time, or we can enter to watch the source files and compile on any changes.
  • Once you have built your application using Bootstrap, you can at the end go through and edit the source files so that 1) you only import the Bootstrap components which you are using and 2) make sure all the components look exactly the way you want them to.

These days, starting a web application is very easy. Using create-react-app along with Bootstrap will give you everything you need.
