With a function component, you can name it anything though. JSX is also a compromise! Go ahead and try and return any other HTML element inside the function above and see how they are all supported for example, return a text input element. Fundamental 2: What the flux is JSX? Example 1 above can be written in pure React.
This is why we used it directly in the ReactDOM. The React. Its list of arguments starting from the 3rd one comprises the list of children for the created element. We were able to nest React. The second argument to React. See how I added a semicolon at the end. The most famous implementation of which is Redux. Flux fits the React reactive pattern perfectly. JSX, by the way, can be used on its own.
Then, we instruct React to use it somewhere. For example, inside a render call of another component, or with ReactDOM. Then, React instantiates an element and gives it a set of props that we can access with this. Those props are exactly what we passed in step 2 above. This is the first of what we call: component lifecycle methods. React then computes the output of the render method the virtual DOM node. Since this is the first time React is rendering the element, React will communicate with the browser on our behalf, using the DOM API to display the element there.
This process is commonly known as mounting. React then invokes another lifecycle method, called componentDidMount. We can use this method to, for example, do something on the DOM that we now know exists in the browser. Prior to this lifecycle method, the DOM we work with was all virtual. Some components stories end here. Other components get unmounted from the browser DOM for various reasons. Right before the latter happens, React invokes another lifecycle method, componentWillUnmount.
The state of any mounted element might change. The parent of that element might re-render. In either case, the mounted element might receive a different set of props. React magic happens here and we actually start needing React at this point! Prior to this point, we did not need React at all, honestly. Fundamental 7: React components can have a private state The following is also only applicable to class components. Now, notice that we updated the state using two different ways: By passing a function that returned an object.
We did that inside the handleClick function. By passing a regular object. We did that inside the interval callback. Fundamental 8: React will react React gets its name from the fact that it reacts to state changes although not reactively, but on a schedule. Fundamental 9: React is your agent You can think of React as the agent we hired to communicate with the browser. A component might need to re-render when its state gets updated or when its parent decides to change the props that it passed to the component If the latter happens, React invokes another lifecycle method, componentWillReceiveProps.
If either the state object or the passed-in props are changed, React has an important decision to do. I could have done with fewer unnecessary to me anecdotes inserted to But I would recommend this book to others and I intend to seek out some of his other books.

He did not need that many pages. He also did quite a bit of humble bragging, which was a pretty big turnoff for me. His own biases were very clear. Overall, some good information, but not worth the slog in my opinion. May 18, Jonathan rated it it was ok.

I have a hard time giving this book such a low score, but I also have many reasons to not give it a very good one either. There for sure is some exceptional information and strong reasoning behind the use and misuse of social media in the world today. It's hard to overlook the light that is brought to critical thinking, weeding out "fake news" and dealing with online trolls. There are some serious problems that need to be addressed and this book will help lead that discussion.
There is also a lot I have a hard time giving this book such a low score, but I also have many reasons to not give it a very good one either. There is also a lot of thought and research placed into what the future of social media and the digital world, in general, will look like and a charge to all of humanity to shift our focus of social media and start using it for a greater purpose.
I guess I was under the assumption that people realized using search engines and social media does not always provide accurate information, but that staggering numbers present in this book scare me. We need to do a better job of not only educating our youth but people in general about how the internet works. Since I started this book it has become glaringly obvious how much crap there is on social media and the chapter on how social media affects your brain wasn't shocking, but it sure was eye-opening. I started by analyzing myself and monitoring my own social media tendencies, but observing others really puts some fear in my heart about what the future means for them.
There is also a solid chapter about privacy protection and being more diligent about what you share not only openly online, but also with user agreements. Some of us are so deep in the hole of what these companies know about us, there is literally no way to get out. I would guess the majority of people who have internet access to even read this review have shared the rights to their privacy with enough companies that computers and algorithms know more about them than they do themselves.
In fact, Goodreads might even be one of those companies. I know I didn't read the "terms of service", so for all I know they might have the rights to my first born child. At best they at least can tell a lot about me just by viewing my likes in books. All this stuff was really good, like everyone on the planet needs to read good. I can only hope that as time goes on Harrison will continue to release new additions to this book as more and more studies are conducted, especially when it comes to the effect on the brain.
The problem though is that the bad in this book is glaringly bad.
Think Before You Act Quotes
First off this book was super repetitive. I found myself reading what I thought was literally the exact same sentence over and over again. There was a spiral effect used throughout where something was mentioned over and over again every fifty pages. There is also an entire chapter that I think adds a lot of value and insight if you focus on the main message, "we live in a social bubble and tend to become friends and follow people with like interests, because of that we end up seeing nothing online except for stuff that we agree with and it gives us a false sense of reality".
This is essentially what happened with the election and I think it is valid to make that point Instead, woven throughout the rest of the book is many backhand comments relating to the author's feelings on President Trump.
How Fast Can You Learn React?
For a book that takes the stance of an objective view on the topic of social media, often presenting both sides of every argument, it becomes clear very quickly that Harrison is a Trump hating liberal. I just found no need for that in this book. The fact that he used his platform to lure people into reading about his political views was a pretty big turn off for me. It was almost as if during these pages I kept thinking about his own advice that he was giving and thinking of how contradictory he was. I don't have any problems with his words on this topic as a stand-alone, but these subjective opinions scattered throughout the book took away a lot of clout for me.
I think he would have been better of releasing a different book under the title "How Trump Won the Election Using Social Media" as this entire chapter felt so out of place and meaningless to the rest of what the book was trying to expose. I do think that most of the topics in this book need to continue to be on the docket of discussions, especially from a government and legal standpoint and I can only hope that we continue to spread education on the subject of social media and we don't travel as a society down the doomsday road that some predicted in this book.
Aug 08, Tim Maddock rated it really liked it. Interesting Perspective Most of the content can be summed up by using common sense and reasonable self discipline while online. Too wordy. The book is full of engaging ideas, and was an interesting read, but has a lot of short comings. Firstly I like Mr Harrison's writing, he does however need a new editor. There was many instances of spelling or grammar errors, and the formating of the book is flat out atrocious and made the book hard to read at times.
The book comes across as more of a newspaper or magazine article in book form. I feel as though the content was stretched a bit thin. The pages of the book could have been appropr The book is full of engaging ideas, and was an interesting read, but has a lot of short comings.
The pages of the book could have been appropriately trimmed to maybe As it stands the impact is lost a lot of the time by constantly referring to 'average peoples' opinions or ideas about the topic It really serves no value to the book, and it unfortunately relies heavily on these anecdotes. Worth reading but large sections can be skim-read without losing anything in the process. Nov 28, Christina rated it really liked it.
