Markaad baadhayso interneedka, boggaga internetka ee aad la falgasho waxa laguu soo bandhigayaa iyadoo la isticmaalayo saddex teknooloji: HTML , CSS , iyo waxa aan kaga hadli doono maqaalkan—JavaScript.

Saddexda, JavaScript waa kan ugu horumarsan. Waxay ku darsataa shaqeyn firfircoon bogagga shabakadda, taas oo ka dhigaysa kuwo aad u adag oo is dhexgal ah. JavaScript la'aanteed , qaar ka mid ah mareegaha aad jeceshahay suurtogal ma noqon doonaan.

Maqaalkan, aan ku kala saarno waxa uu yahay JavaScript , sida uu u shaqeeyo, iyo isticmaalka badan ee online-ka ah.

Waa maxay JavaScript?^{(What Is JavaScript?)}

JavaScript waa luuqad qoraal ah. HTML , mid ka mid ah qaraabadiisa ugu caansan, waa luqad calaamadeysan. Farqiga ugu weyn ee u dhexeeya labada waa in luqadaha calaamadaynta ay yihiin qaab dhismeed oo ay diyaariyaan muuqaalka iyo naqshadeynta bogga. Luqadda calaamadaynta ayaa si shaqaynaysa soo bandhigaysa, halka luqadda qoraalku ay tahay mid macquul ah iyo algorithmic.

Erayada caadiga ah, HTML waxay bedeshaa qaabka boggaga shabakadu u eegaan halka JavaScript ay dhab ahaantii bixiso shaqaynta xisaabinta. HTML , ma jirto qaab xitaa lagu qiimeeyo isla'egta fudud sida 1 + 1. JavaScript ayaa taas samayn kara iyo wax ka badan.

JavaScript waxaa laga hirgelin karaa labada dhinac ee server-ka iyo dhinaca macmiilka. JavaScript -ka dhinaca macmiilka ah ayaa ugu badan, halkaas oo koodhka JavaScript lagu tixraaco HTML oo uu u tarjumo biraawsarkaaga. Koodhkani wuxuu qaban karaa wax badan oo ka badan oo kaliya inuu beddelo muuqaalka bogga, sida si firfircoon u soo saarida nuxurka HTML , waydiiso gelinta isticmaalaha, iyo in ka badan.

Si aan u soo koobo, JavaScript waa luuqad qoraal ah oo la tarjumo oo fudud, taas oo kor u qaadi karta isdhexgalka website-ka.

Sidee Loo Isticmaalaa JavaScript Online?^{(How Is JavaScript Used Online?)}

Si la mid ah luuqad kasta oo wax lagu qoro, fursadaha ayaa ku xaddidan oo kaliya waxaad la imaan karto. Haddii aad leedahay xirfado oo aad ku riyoon karto, waa inaad awood u leedahay inaad sameyso.

Si kastaba ha ahaatee, waxaa jira qoraallo JavaScript ah oo caan ah oo shabku aanu la mid ahaan doonin la'aanteed. Aynu ka wada hadalno dhowr ka mid ah kiisaska ugu caansan ee loo isticmaalo JavaScript .

Xaqiijinta Foomka

Haddii aad waligaa buuxinaysay foom is-diiwaangalin ah oo kaliya in laguu sheego in isticmaale-magacaaga ama eraygaaga sirta ah uu aad u gaaban yahay, taasi waxay ahayd JavaScript !

Ansixinta foomka^(Form) waxa lagu samayn karaa tiro luuqado qoraal ah oo kala duwan, laakiin JavaScript waxa ay u ogolaataa in si firfircooni ah loo sameeyo oo aan la soo dhejin wax xog ah. Tani waxay hoos u dhigi kartaa kharashka server-ka iyada oo loo marayo xawaaraha hoos u dhaca, waana hab fiican oo looga hortago niyad-jabka dhinaca isticmaalaha.

Marna ma fududa in aad foom soo gudbiso kadibna laguu sheego in macluumaadkaagu aanu sax ahayn. JavaScript ayaa tan ku samayn kara duullimaad.

Beddelayaasha & Xisaabiyeyaasha

Hadday tahay Fahrenheit ilaa Celsius , USD ilaa EUR , ama wixii la mid ah, u beddelashada xogta si firfircooni waa wax JavaScript ka sarreeya. Haddii aad waligaa qaadato koorsada JavaScript , mid ka mid ah casharradaada ugu horreeya waxay u badan tahay inay abuurto shay sida xisaabiyaha heerka ribada^{(interest rate calculator)} . Waa waayo-aragnimo waxbarasho oo weyn oo soo bandhigtay qaar badan oo ka mid ah aasaaska JavaScript .

JavaScript -dhinaca macmiilka waa mid ka mid ah xalalka ugu fiican marka ay timaado maaraynta xisaabaadka sida kuwan oo kale.

Soosaarayaasha Random

Math.random () waa shaqo ay jecel yihiin dad badan oo JavaScript jecel, aad bayna faa'iido u leedahay. Waxay u ogolaataa abuurista lambar aan toos ahayn, oo sabbaynaysa inta u dhaxaysa 0 iyo 1, taas oo awood u siinaysa qoraallo badan oo xariif ah.

Mid ka mid ah qoraallada ugu caansan ee noocaan ah waa koronto dhaliye ^{(random )}p assword ah^{(assword generator)} . Waxaad kuwan ka heli kartaa shabakada oo dhan, waxayna yihiin ilo lagu kalsoonaan karo oo ah jiilka sirta ah ee random maadaama JavaScript -ka macmiilka aanu wax xidhiidh ah la lahayn server-ka, sidaa darteed waligiis lama kaydin ama lama kaydin muuqaalada gadaashiisa.

Ciyaaraha

Taasi waa sax- JavaScript xitaa waxaa loo isticmaali karaa in lagu codeeeyo ciyaarahaaga. Halka JavaScript^(JavaScript) -dhinaca macmiilku aanu u oggolaan doonin taageerada nooc kasta oo khadka ah, waayo-aragnimada iskaashiga, ciyaaraha hal-ciyaaryahan ama ciyaaraha ay ku ciyaari karaan laba isticmaale isla kiiboodhka ayaa gabi ahaanba suurtogal ah.

Waa kuwan dhawr tusaale oo caadi ah:

JavaScript waa luuqad qoraal ah oo aad u wanaagsan oo ka shaqeysa xitaa mashaariicda aan aadka u culusayn!

Haddii aad horeba si fiican u taqaan HTML iyo CSS , JavaScript waa tallaabo xigta oo weyn oo runtii kor u qaadi karta ciyaarta koodhkaaga. Haddi codeeyntu aysan ahayn dantaada, maqaalkani waa inuu kaa caawiyaa qiimaynta shaqaynta luuqadda qoraalkani u keentay malaayiin mareegaha internetka ah. Intarneedku isku mid ahaan maayo JavaScript la'aanteed .

HDG Explains: What Is JavaScript & What Is It Used For Online?

When you browse the internet, the web pages yоu interact with аre presented to you using three technologies: HTML, CSS, аnd what wе’ll discuss in this artiсle—JavaScript.

Of the three, JavaScript is the most advanced. It adds dynamic functionality to web pages, which make them much more complex and interactive. Without JavaScript, some of your favorite websites wouldn’t be possible.

In this article, let’s break down what JavaScript is, how it works, and the many uses for it online.

What Is JavaScript?

JavaScript is a scripting language. HTML, one of its most popular relatives, is a markup language. The major difference between the two is that markup languages are structural and prepare the look and design of a page. A markup language is functionally presentational, whereas a scripting language is logical and algorithmic.

In layman’s terms, HTML changes the way web pages look while JavaScript actually offers computational functionality. In HTML, there’s no way to even evaluate a simple equation such as 1 + 1. JavaScript can do that and so much more.

JavaScript can be implemented on both the server and client side. Client-side JavaScript is most common, where JavaScript code is referenced via HTML and interpreted by the web browser. This code can do a lot more than just change the appearance of a page, such as dynamically generate HTML content, ask for user input, and more.

To put it short, JavaScript is a lightweight, interpreted scripting language that can enhance the interactivity of a website.

How Is JavaScript Used Online?

As with practically every scripting language, the possibilities are limited only to what you can come up with. If you have the skills and you can dream it, you should be able to make it.

However, there are some very common JavaScript scripts that the web would not be the same without. Let’s discuss a few of the most popular use cases for JavaScript.

Form Validation

If you’ve ever been filling out a signup form only to be told that your username or password was too short, that was JavaScript in action!

Form validation can be performed in a number of different scripting languages, but JavaScript allows it to be done dynamically and without posting any data. This can cut down server costs through lowered bandwidth, and it’s a great way to prevent frustration on the side of the user.

It’s never fun to submit a form and be told afterwards that your information wasn’t valid. JavaScript can do this on the fly.

Converters & Calculators

Whether it be Fahrenheit to Celsius, USD to EUR, or the like, dynamically converting data is something JavaScript excels at. If you ever take a course on JavaScript, one of your first few lessons will likely be to create something such as an interest rate calculator. It’s a great learning experience that introduces many of the fundamentals of JavaScript.

Client-side JavaScript is one of the best solutions for when it comes to handling calculations such as these.

Random Generators

Math.random() is a favorite function for many JavaScript lovers, and it’s extremely useful. It allows the creation of a random, floating-point number between 0 and 1, which enables a lot of clever scripts.

One of the most popular scripts of this kind is a random p assword generator. You can find these all over the web, and they’re a trustworthy source of random password generation since client-side JavaScript has no interaction with the server, so it’s never cached or saved behind the scenes.

Games

That’s right—JavaScript can even be used to code your own games. While client-side JavaScript won’t allow support for any kind of online, co-operative experience, single-player games or games that can be played by two users at the same keyboard are entirely possible.

Here are a few classic examples:

JavaScript is a seriously good scripting language that works even for not-so-serious projects!

If you’re already well-versed in HTML and CSS, JavaScript is a great next step that can really enhance your coding game. If coding isn’t your interest, this article should help in appreciating the functionality this scripting language has brought to millions of websites. The internet wouldn’t be the same without JavaScript.
