海外TECH	DEV Community	The World Of React Events	https://dev.to/developerioweb/the-world-of-react-events-59ej	The World Of React Events WhatEvent occur when a user or the browser manipulate a page For Ex →Page Loading clicking a Button Pressing any Key Closing a window These all are the events We as a developer use these Events to manipulate things in the site In the Case of React Events they are not actually the DOM Events they are called Synthetic Events Synthetic Events →These are the Wrappers that React uses to standardise event functionality across browser But what is the need of Synthetic Events Actually Events are not the part of Core JavaScript they come from each browser s JavaScript API means Each browser will handle them differently So in React we have the Synthetic Events which makes the consistency across all the browser HowSo we have many types of the Synthetic Events including keyboard events form events mouse events etc Some of them are onClickonContextMenuonDoubleClickonDragonDragEndonDragEnteronDragExitonDragLeaveonDragOveronDragStartonDroponMouseDownonMouseEnteronMouseLeaveonMouseMoveonMouseOutonMouseOveronMouseUpFor more visit this link SyntheticEvent ReactExample →when ever u try to hover on the Smily It will log a Proverb and if try to copy the text it will give u an alert App js import App css import React Component from react import CopyDemo from CopyDemo import Messenger from Messenger class App extends Component render return lt div gt lt Messenger gt lt CopyDemo gt lt div gt export default App CopyDemo js import

Method Bindingclass Messenger extends Component static defaultProps messages All good things come to an end A journey of a thousand miles begins with a single step Actions speak louder than words An apple a day keeps the doctor away handleMouseEnter console log THIS IS this undefined const messages this props const rand Math floor Math random messages length console log messages rand render return lt div className App gt lt h gt Proverbs lt h gt lt div onMouseEnter this handleMouseEnter style width px backgroundColor Red margin auto gt lt div gt lt div gt If u try to run this it will give an TypeError Also if we console log the value of this we will see the value of undefined Ways to fix this problem → Use Inline BInd → Cons New Function is Created on every render Like above we have Created a Function handleClick and bind it using inline bind but when we check if they are equal or not so it return false So this means that a New Function is created when it renders Arrow Function →Pros →No mention of Bind Cons →Intent less clearnew function created on every render In the Constructor →Only need to bind once Bonus One →handleClick gt console log This is this This will also used to bind Method Binding with Arguments →In the previous example our this handleClick didn t take any argument To Pass the Argument we can write like this onClick this handleClick bind this lt argument name gt ORonClick gt this handleclick argument name When we are using the Arrow function we have to use the Curly braces while calling the function Passing Functions to the child Component →Children are often not stateful but they need to tell parent to change the state But how can we send the data back to the parent Component Data FlowA parent Component defines the Function The function is passed as a prop to a child component The child component invokes the prop The parent function is called usually setting new state The parent component is re rendered along with its children One way to pass the Function →we have to make something like this whenever we click on the cross button the corresponding Number should Disappear Numlist jsimport React Component from react import NumberItem from NumberItem class NumberList extends Component constructor props super props this state nums remove num this setState st gt nums st nums filter n gt n num render let num this state nums map n gt lt NumberItem value n remove this remove bind this n gt console log num return lt ul gt num lt ul gt export default NumberList In this we have passed the remove function as props to the NumItem Component NumItem jsimport React Component from react class NumberItem extends Component render return lt li gt this props value lt button onClick this props remove gt X lt button gt lt li gt export default NumberItem This code works fine but as we remove the elements the Numlist Component get Re rendered and we are binding the method remove inline So every time the component get rendered new function created To solve this we have to bind the method in the Constructor import React Component from react import BetterNumberItem from BetterNumberitems class BetterNumberList extends Component constructor props super props this state nums this remove this remove bind this remove num console log num this setState st gt nums st nums filter n gt n num render let num this state nums map n idx gt lt BetterNumberItem value n remove this remove gt return lt ul gt num lt ul gt export default BetterNumberList import React Component from react class BetterNumberItem extends Component constructor props super props this handleRemove this handleRemove bind this handleRemove this props remove this props value render return lt li gt this props value lt button onClick this handleRemove gt X lt button gt lt li gt export default BetterNumberItem Earlier we are passing the argument to the remove method but now we aren t so if we just try to console log what is passed to remove we got the events So we call handleRemove function and in that we call the remove function and pass the argument to it NumList Naming Convention → List and keysKeys help React identify which items have changed are added or are removed Keys should be given to the elements inside the arrayand I have also learnt how to write the Functional Component Day Completed	2022-01-14 20:18:38

海外TECH	Engadget	Google Meet’s second-screen Companion Mode is coming to the Nest Hub Max	https://www.engadget.com/google-meet-companion-mode-rolling-out-to-the-nest-hub-max-195017337.html?src=rss	Google Meet s second screen Companion Mode is coming to the Nest Hub MaxAfter updating Workspace formerly G Suite with a number of new features last year Google s previously announced Companion Mode for the Nest Hub Max and other Google Meet hardware has begun rolling out Companion Mode is a second screen experience designed to support the shift towards hybrid working environments by providing easier access to various Google Meet controls and features for people calling in from a shared office Previously workers who called in from a meeting room often had to jockey for control if they wanted to do simple things like raise their hand virtually or drop a comment in chat The result was that employees who worked remotely and called into meetings using a phone or PC were often more active and visible in meetings than their colleagues at the office who participated using a traditional conference room set up However thanks to the addition of Companion Mode office workers will soon get access to most of Google Meet s features via Nest Hub Max or other certified hardware like a Lenovo Tap while still being part of the shared meeting And while the Nest Hub Max might not be a common sight in conference rooms today this new mode could help Google push more devices to businesses of all sizes as they adapt to post pandemic working arrangements To join a meeting using Companion Mode you can either activate the setting in Google Meet s “green room or by using a dedicated URL g co companion Google Meet features available in Companion Mode include chatting starting and voting on polls raising your hand which includes displaying a person s name and title using host controls and turning on captions or translations Google says the goal is to ensure that regardless of where you re working from everyone in a video call will have access to a similar set of tools and features Companion Mode will be enabled by default though for people using the free version of Meet it s important to note that anyone using it will count as an additional participant towards the person limit instead of a room full of people counting as a single attendee Companion Mode in Google Meet is rolling out this week though depending on your domain or user type it may take another few weeks for it to be available on your device	2022-01-14 20:05:17
