海外TECH	DEV Community	7 Techniques to Optimize React Applications Performance	https://dev.to/sanikommushirisha/efficient-components-techniques-to-optimise-react-applications-performance-3l9l	Techniques to Optimize React Applications PerformanceOptimizing the performance of a React application is an important aspect of maintaining a high quality user experience It requires deeper understanding of React framework various phases of the components lifecycle and profiling tools to measure bottlenecks and analyze performance There are several techniques you can use to improve the performance of your React application Below are some tips you can follow to optimize React performance Use the shouldComponentUpdate lifecycle method to avoid unnecessary re renders This method allows you to control when a component is updated by determining if the new props or state are different from the previous ones Use the PureComponent class instead of the Component class for components that do not require complex logic Pure components implement the shouldComponentUpdate method with a shallow comparison of the props and state so they only re render if the props or state have changed Use the React memo higher order component to optimize functional components This is similar to PureComponent but it can be used with functional components instead of class based components Use the React lazy and React Suspense components to lazy load components that are not immediately needed This can improve initial loading time by only loading the necessary components on demand Use the useCallback and useMemo hooks to optimize functions and computed values within components These hooks allow you to memoize values and functions so that they are not re created unnecessarily Use the React Fragment component to avoid unnecessary wrapper elements in your components Wrapper elements such as divs can add extra nodes to the DOM which can affect performance React Fragment allows you to return multiple elements from a component without adding extra nodes to the DOM Use Immutable Data Structures as they are more efficient to compare than mutable data structures They have zero side effects simpler to create test and use and can prevent unnecessary re rendersBonus Tip Use the profiler built into React to identify performance bottlenecks and optimize the rendering of your components The profiler can help you understand which components are rendering frequently and why allowing you to make changes to improve their performance By following these tips you can improve the performance of your React application and provide a better user experience for your users It is also important to regularly monitor and profile your application to identify areas for optimization and ensure that it continues to perform well	2022-12-10 11:08:31
海外TECH	Engadget	Uber files lawsuit to block NYC driver pay increase	https://www.engadget.com/uber-files-lawsuit-block-nyc-driver-pay-increase-111506195.html?src=rss	Uber files lawsuit to block NYC driver pay increaseBack in November New York City s Taxi and Limousine Commission TLC voted to increase the pay rates of Uber and Lyft drivers to make up for the rise in inflation and and operational costs The new rates were supposed to be implemented on December th but now Uber has sued the commission to block the new rates from taking effect According to Bloomberg Uber said in its lawsuit that it would have to spend an additional million to million a month if the new rates are implemented and that it wouldn t be able to recover those costs without raising fares To note drivers per minute rates are going up by percent and per mile rates by percent under the new rules That means for a mile trip that takes minutes a driver would earn at least which is more than current rates The drivers are also getting another pay bump in March based on inflation rates comparing December s to September s this year A company spokesperson told the news publication that by increasing drivers pay this December TLC is locking in quot this summer s high gas prices in perpetuity quot They added that TLC quot should have followed its usual annual adjustment and instituted a temporary gas surcharge when gas prices were actually elevated quot instead nbsp The company s lawsuit seems to indicate that it intends to pass the costs associated with drivers pay increase to riders quot Such a significant fare hike right before the holidays would irreparably damage Uber s reputation impair goodwill and risk permanent loss of business and customers quot its lawsuit said In a strongly worded response to the lawsuit TLC said acknowledged that Uber already charges percent more today compared to but it said that the company is keeping money earned from fare hikes over the past few years to itself nbsp The commission s statement reads quot Just in time to steal Christmas from New York families Uber is suing to stop the raise the TLC enacted for app drivers after months of public hearings years of stalled wages and the pandemic decimating incomes Uber s Grinch move is on top of denying a fuel surcharge to only NYC drivers when costs skyrocketed due to record high inflation forcing drivers in one of their most profitable markets to choose between groceries and fueling up nbsp Uber is already charging passengers more today compared to AND KEEPING IT FOR THEMSELVES but says this modest raise for drivers is what will break the company Shame on you Dara Khosrowshahi We call on the City to stand firm and defend the rights of drivers to labor with dignity Uber seeks chaos We seek dignity We are confident we will prevail quot The ride hailing giant is now asking the court to declare the new pay rates as invalid and to prevent the first increase s implementation this month while the lawsuit is ongoing nbsp	2022-12-10 11:15:06
