海外TECH	DEV Community	Explaining SOLID with LEGO (and probably making enemies in the tech community)	https://dev.to/noriller/explaining-solid-with-lego-and-probably-making-enemies-in-the-tech-community-4db4	Explaining SOLID with LEGO and probably making enemies in the tech community Yeah so this time I ll be doing something a little different I believe I have a way to explain how SOLID works with LEGO And I m already preparing for people making a enemy of me because of that What is SOLID The textbook AKA Wikipedia definition is Five design principles intended to make software designs more understandable flexible and maintainable It was promoted by Uncle Bob and the acronym was introduced by Michael Feathers And even without using all of the SOLID principles your code will always be better BTW Do I know everything there is to know about SOLID Noooo But ever since I ve started thinking of it as LEGOS they started making a lot more sense to me and I hope it will do the same for you To understand what I m talking I ll be assuming you know what LEGO is because if you don t well I m sorry for you or Welcome to Earth S The Single responsibility principleThere should never be more than one reason for a class to change Take a look at the cover photo again why are there so many different pieces Because each one does ONE thing Let s say you re making something out of LEGO if you need a yellow brick you don t need to cut another larger piece you just need the one piece you want You need other color No need to recolor it just take the appropriate piece The pieces itself never change O The Open closed principle Software entities should be open for extension but closed for modification Can you change a LEGO brick No you can t But what if you need a bigger piece You ll either take an already bigger piece or you will make one by combining smaller pieces Each brick being immutable by itself how do you do that You use the knobs and tubes to connect one to another you extend them without modifying them L The Liskov substitution principleFunctions that use pointers or references to base classes must be able to use objects of derived classes without knowing it This one is a little trick with LEGO alone But think it this way what if I D Print a piece The knobs and tubes in either one don t care if there s a brand or the right brand they only care if it fits or not I The Interface segregation principleMany client specific interfaces are better than one general purpose interface Again look at the cover photo Would it even be possible to make anything if pieces wanted to be ALL pieces You would have one big piece what would be too much on all situations Maybe all you wanted is a little brick with one knob but instead you have a gigantic thing that just don t fit If it won t be using everything you just use the right piece for the job D The Dependency inversion principleDepend upon abstractions not concretions More than just plastic pieces you have stuff made out of LEGO that you wouldn t believe Electric toys prosthetic limbs drones And how is that possible Have you ever seen motors batteries circuit boards with knobs and tubes No because you don t need them You hide them behind an abstraction that will have the knobs and tubes and that abstraction will connect with the rest You don t need special parts that will fit the LEGO you just need to encapsulate it in a way that you can use that instead Little pieces that you aggregate one by one multiples by multiples and that makes a bigger and more complex things LEGO and programming who knew right Cover Photo by Xavi Cabrera on Unsplash	2021-10-24 23:31:09
海外TECH	DEV Community	Conditional logic you should know	https://dev.to/mcube25/conditional-logic-you-should-know-3bad	Conditional logic you should knowOnce you start getting JavaScript under the belt one of the things you would want to do is get conditional logic into an application What is conditional logic Conditional logic acts as a traffic curve in a program It decides which conditions are to be prioritized if the logic is true It also decides the code to run or what to do if the condition is false This conditions can be used to run different things based on different values Let us take a look at different conditional logic in javaScript We want to know what they look like and when they are to be used to optimize an application If else statementWe are going to look at an array of food and each food is represented an objects const food type Banana family fruits type Lettuce family vegetable type Rice family grains We are going to use a javascript forEach method to loop through the contents of the food array and execute the function using the if else statement food forEach type family gt if family fruits console log i am eating type if family Vegetable console log i am eating type if family grains console log i am eating type When we run the above code we get the current value that we loop over and introduce our conditional logic All we are doing is saying if the condition is met run the code or other wise move to the next statement That is the basic idea behind an if statement It is a very simple but powerful tool We can apply an else statement to the if statement For example we can sayfood forEach type family gt if family fruits console log i am eating type else if family Vegetable console log i am eating type else if family grains console log i am eating type else console log all food are good for hunger When we give a condition to the if statement if the condition is true we are going to log a statement otherwise we log whatever the else statement is when the if statement is through no matter the value we are looping through As long as it does not meet our if statement the else statement will be logged Switch statementThe next type of logic we are going to look at is the switch statement The switch statement is similar to the if else statement We going to take a look at a similar food array and loop through using the switch statementconst getFoodAll food gt switch food case Banana return this is my favorite fruit case Lettuce return this is my favorite Vegetable case Rice return this is my favorite grain default return i have no business being here Unlike if else statements the switch statements keep going They do what is called fall through What it does is print all the statements when the conditions are met To prevent all the statements falling through a break statement is added const getFoodAll food gt switch food case Banana return this is my favorite fruit break case Lettuce return this is my favorite Vegetable break case Rice return this is my favorite grain break default return i have no business being here When using the switch statement in some cases we want to fall through all the various cases In some other cases we want to break the code when we have our result The break is known as the stop mechanism for achieving this When we hit a statement we want evaluated the break stops the code from evaluating all other statements from that point This break stops the steady flow If we don t have a break the code is going to run to the default statement The switch statement is super useful in replacing logic that uses a lot of if else statements Ternary operatorIt is a simple piece of very powerful code It is the only JavaScript operator that takes three operands a condition followed by a question mark then an expression to execute if the condition is truthy followed by a colon and finally the expression to execute if the condition is falsy This operator is frequently used as a shortcut for the if statement function lifeStyle if condition return value else if condition return value else if condition return value else return value Using the tenery operator the above logic can be simplified intofunction lifeStyle return condition value condition value condition value value	2021-10-24 23:14:18
