海外TECH	DEV Community	Javascript 1O1 series : Functions	https://dev.to/osam1010/javascript-1o1-series-functions-4g9c	Javascript O series Functions You ll learn How to declare and define functions Passing arguments and parameters as well as return values at the end of the function as well as using anonymous functions What is function A JavaScript function is a block of code designed to perform a particular task A JavaScript function is executed when “something invokes it calls it wschools Functions are one of the fundamental building blocks in JavaScript A function in JavaScript is similar to a procedure ーa set of statements that performs a task or calculates a value MDNFunctions are simply block of code that wrote once but can be used many times Syntax function name parameters functions logic here function keyword identifier as name for the function parentheses so it can hold parameters or not and then curly brackets that will hold the code inside Why we need to use functions when we write javascript code any statement or expressions will be executed only once unless it s inside a loop or under conditionals statements and if we need to use particular statements we ll have to write all again and again whenever we need that statements when using function we simply put some code or statements inside of a block and give it unique name and then we can reuse that code block whenever we want by just calling it s name as you see it s very hard and painful and not even makes sense if we code like this so let s see how it turns we use functions Parameters and arguments every function do specific task these task may need some data from outside to get things done if our function needs some data which is lay out of it how can we pass the needed data to it i introduce parameters for youparameters are simply variables to store data coming from outside of the function and make it available to the function to make use of it imagine someone want to give you something what would you do often you ll open your hands to take it from that person as well as function has parameter to store the data has been send to it for using it to perform some operations Parameter RulesJavaScript function definitions do not specify data types for parameters JavaScript functions do not perform type checking on the passed arguments JavaScript functions do not check the number of arguments received wschoolsHow to declare Parameters the good thing is parameters variables doesn t need to be declared in explicit way as other variables like var let or const you just name the needed parameters and they will be variable that available inside the function body What is arguments The function s variables that we declared to receive data for the function we call it parameters and these passed parameters values are called arguments so the function variable that used to hold data from outside is parameter and the passed value to that function from outside is argument ok more about parameters and argument JavaScript Function Parameters GeeksforGeeks A Computer Science portal for geeks It contains well written well thought and well explained computer science and programming articles quizzes and practice competitive programming company interview Questions geeksforgeeks org wschools com Function Expressions A JavaScript function can also be defined using an expression A function expression can be stored in a variable The function above is actually an anonymous function a function without a name Anonymous function is a function that does not have any name associated with it Normally we use the function keyword before the function name to define a function in JavaScript however in anonymous functions in JavaScript we use only the function keyword without the function name geeks for geeksFunctions stored in variables do not need function names They are always invoked called using the variable name also you can use anonymous function with the new syntax arrow functionsArrow functions An arrow function expression is a compact alternative to a traditional function expression but is limited and can t be used in all situations There are differences between arrow functions and traditional functions as well as some limitations Arrow functions don t have their own bindings to this or super and should not be used as methods Arrow functions don t have access to the new target keyword Arrow functions aren t suitable for call apply and bind methods which generally rely on establishing a scope Arrow functions cannot be used as constructors Arrow functions cannot use yield within its body MDN What is return statement Description When a return statement is used in a function body the execution of the function is stopped If specified a given value is returned to the function caller MDNto reuse some code or some logic we wrap it in a function but what if we also to reuse this function output like using its value inside a loop or use it in conditional statements or pass it to another functions or whatever elsethen you need to use RETURNwhat return do is simply evaluate some value and put it as the function value if we returned in a function we can say the function s value is it s not exactly this way just assume it s like this to understand how to use return also return stop executing the function thus any code that after return will never be executed References and useful links google com JavaScript Functions This tutorial introduces you to JavaScript functions that structure your code into smaller reusable units javascripttutorial net programiz com Functions JavaScript MDN Functions are one of the fundamental building blocks in JavaScript A function in JavaScript is similar to a procedureーa set of statements that performs a task or calculates a value but for a procedure to qualify as a function it should take some input and return an output where there is some obvious relationship between the input and the output To use a function you must define it somewhere in the scope from which you wish to call it developer mozilla org Thanks for reading feel free to ask any question about javascript or about this series I appreciate any feedback or advises to improve My content find me on twitter github and my portfolio	2022-04-19 06:13:09
海外TECH	DEV Community	Apache ShardingSphere 5.1.1 Is Available	https://dev.to/apache_shardingsphere/apache-shardingsphere-511-is-available-3c3d	Apache ShardingSphere Is AvailableIn less than two months since the release of Apache ShardingSphere our community has merged PRs from teams or individuals around the world to bring you the new release This release has a number of optimizations in terms of features performance testing documentation examples and more The performance aspect deserves special mention as we adopt the industry standard TPC C test model to run Apache ShardingSphere and the openGauss database on physical servers achieving over million tpmC the best performance in the industry at the same scale This article is an overview of the ShardingSphere update Apache ShardingSphere update optimizes the functionality and performance of and fixes some issues The following will give you a general overview of some of the updates KernelThe kernel is ShardingSphere s foundation and it remains our goal to build a fully functional and stable kernel with high performance In ShardingSphere optimizes a lot of logic at the kernel level fixing the problems found in different scenarios in the previous version including data sharding read write splitting data encryption and improved the performance of each scenario to varying degrees In terms of database dialects the kernel improves the support for MySQL tablespaces and improves SQL support for Oracle SQL Server PostgreSQL openGauss and other databases Additionally the initial support for PostgreSQL openGauss schema a three tier structure has been implemented in the ShardingSphere kernel and will be improved with the future releases InterfaceThis update fixes a potential performance risk for ShardingSphere JDBC optimizes the non essential interaction logic between internal ShardingSphere JDBC and the database connection pool and reduces the performance overhead of ShardingSphere JDBC In terms of ShardingSphere Proxy support for MySQL PostgreSQL data types has been improved The occasional ResultSet closed error for ShardingSphere Proxy MySQL has been fixed and ShardingSphere Proxy MySQL also has initial support for executing multiple statements at the protocol level to improve the performance of batch operations In terms of client support ShardingSphere Proxy PostgreSQL improves the support for PostgreSQL JDBC Driver x and ShardingSphere Proxy openGauss improves the support for openGauss JDBC Driver Elastic Scale outIn this update in addition to fixing the problem that migration tasks cannot be restarted by DistSQL after reporting errors the elastic scaling has been improved and new features of stop source writing resume source writing and partial tables scaling have been implemented For cases that do not meet the migration conditions elastic scale out can fail quickly and find out the problem in time to avoid extra time costs for users DistSQLDistSQL has been optimized in terms of user experience adding more calibration and reducing the possibility of user configuration errors in using DistSQL We also fixed an issue where some user input conflicted with DistSQL keywords Distributed GovernanceIn terms of read write splitting and database discovery in addition to the original MGR MySQL adds a new database discovery method by querying primary secondary delay which can automatically switch read write splitting data sources by getting the secondary delay reducing the threshold for users to use dynamic read write splitting In cluster mode the metadata storage structure has been optimized and reconstructed and the problems caused by ZooKeeper session timeout and case mismatch on table names have been fixed Distributed TransactionsIn terms of transactions ShardingSphere JDBC adds support for Savepoint and ShardingSphere Proxy adds support for Savepoint in XA scenarios in addition to the original support for Savepoint for LOCAL transactions When Narayana is used as an XA implementation ShardingSphere supports the configuration of Narayana to make the use of XA more conveniently With PostgreSQL openGauss when an exception occurs in a transaction ShardingSphere can properly abort the transaction and automatically roll back The above is an introduction to some of the updates to Apache ShardingSphere please refer to the update log for details The ShardingSphere community will be releasing detailed explanations of some of these features so stay tuned ShardingSphere has no changes at the API level but has made many improvements in functionality and performance ーyou re welcome to try it out Update Log New FeaturesKernel PostgreSQL supports alter materialized viewKernel PostgreSQL supports declaresyntaxKernel PostgreSQL
