 ```smart header="Nega <u>Java</u>Script?"
 JavaScript yaratilganda, u dastlab "LiveScript" nomi bilan taqdim etilgan edi. Ammo Java o'sha paytlarda juda mashhur edi, shuning uchun Java tilining "ukasi" sifatida yangi tilni taqdim etish g'oyasi JS mashhur bo'lishga yordam beradi deb hisoblangan .
-=======
-```smart header="Why is it called <u>Java</u>Script?"
-When JavaScript was created, it initially had another name: "LiveScript". But Java was very popular at that time, so it was decided that positioning a new language as a "younger brother" of Java would help.

-=======
-- [CoffeeScript](http://coffeescript.org/) is a "syntactic sugar" for JavaScript. It introduces shorter syntax, allowing us to write clearer and more precise code. Usually, Ruby devs like it.
-- [TypeScript](http://www.typescriptlang.org/) is concentrated on adding "strict data typing" to simplify the development and support of complex systems. It is developed by Microsoft.
-- [Flow](http://flow.org/) also adds data typing, but in a different way. Developed by Facebook.
-- [Dart](https://www.dartlang.org/) is a standalone language that has its own engine that runs in non-browser environments (like mobile apps), but also can be transpiled to JavaScript. Developed by Google.
-- [Brython](https://brython.info/) is a Python transpiler to JavaScript that enables the writing of applications in pure Python without JavaScript.
-- [Kotlin](https://kotlinlang.org/docs/reference/js-overview.html) is a modern, concise and safe programming language that can target the browser or Node.
-
-There are more. Of course, even if we use one of transpiled languages, we should also know JavaScript to really understand what we're doing.
-
-## Summary
-
-- JavaScript was initially created as a browser-only language, but it is now used in many other environments as well.
-- Today, JavaScript has a unique position as the most widely-adopted browser language with full integration in HTML/CSS.
-- There are many languages that get "transpiled" to JavaScript and provide certain features. It is recommended to take a look at them, at least briefly, after mastering JavaScript.

-# Manuals and specifications
+Bu kitob *qo'llanma*dir. U sizga tilni bosqichma-bosqich o'rganishda yordam berish maqsadida yozilgan. Ammo asoslar bilan tanishgandan so'ng, sizga boshqa manbalar kerak bo'ladi.
 
-This book is a *tutorial*. It aims to help you gradually learn the language. But once you're familiar with the basics, you'll need other sources.
+## Xususiyat
 
-## Specification
+[ECMA-262 xususiyatsi](https://www.ecma-international.org/publications/standards/Ecma-262.htm) JavaScript haqida eng chuqur, batafsil va rasmiy ma'lumotlarni o'z ichiga oladi. U tilni belgilaydi.
 
-[The ECMA-262 specification](https://www.ecma-international.org/publications/standards/Ecma-262.htm) contains the most in-depth, detailed and formalized information about JavaScript. It defines the language.
+Ammo shunchalik rasmiy bo'lganligi sababli, dastlab tushunish qiyin. Shuning uchun agar sizga til tafsilotlari haqida eng ishonchli ma'lumot manbai kerak bo'lsa, xususiyat to'g'ri joy. Ammo u kundalik foydalanish uchun emas.
 
-But being that formalized, it's difficult to understand at first. So if you need the most trustworthy source of information about the language details, the specification is the right place. But it's not for everyday use.
+Har yili yangi xususiyat versiyasi chiqariladi. Bu nashrlar orasida eng so'nggi xususiyat loyihasi <https://tc39.es/ecma262/> da joylashgan.
 
-A new specification version is released every year. In-between these releases, the latest specification draft is at <https://tc39.es/ecma262/>.
+"Deyarli standart" deb ataladigan ("3-bosqich") xususiyatlarni o'z ichiga olgan yangi ilg'or xususiyatlar haqida o'qish uchun <https://github.com/tc39/proposals> dagi takliflarni ko'ring.
 
-To read about new bleeding-edge features, including those that are "almost standard" (so-called "stage 3"), see proposals at <https://github.com/tc39/proposals>.
+Shuningdek, agar siz brauzer uchun ishlab chiqayotgan bo'lsangiz, qo'llanmaning [ikkinchi qismida](info:browser-environment) yoritilgan boshqa xususiyatlar ham mavjud.

+- **MDN (Mozilla) JavaScript Reference** misollar va boshqa ma'lumotlar bilan asosiy qo'llanmadir. Alohida til funksiyalari, metodlari va boshqalar haqida chuqur ma'lumot olish uchun ajoyib.
 
-- **MDN (Mozilla) JavaScript Reference** is the main manual with examples and other information. It's great to get in-depth information about individual language functions, methods etc.
+  Uni <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference> da topishingiz mumkin.
 
-    One can find it at <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference>.
+Garchi ko'pincha internet qidiruvidan foydalanish yaxshiroqdir. So'rovda "MDN [atama]" dan foydalaning, masalan `parseInt` funksiyasini qidirish uchun <https://google.com/search?q=MDN+parseInt>.
 
-Although, it's often best to use an internet search instead. Just use "MDN [term]" in the query, e.g. <https://google.com/search?q=MDN+parseInt> to search for `parseInt` function.
+## Moslik jadvallari
 
-## Compatibility tables
+JavaScript rivojlanayotgan til, yangi xususiyatlar muntazam ravishda qo'shiladi.
 
-JavaScript is a developing language, new features get added regularly.
+Brauzer va boshqa dvigatellar orasidagi qo'llab-quvvatlashni ko'rish uchun:

+- <https://kangax.github.io/compat-table> - til xususiyatlari va ularni qo'llab-quvvatlovchi yoki qo'llab-quvvatlamaydigan dvigatellar jadvali.
 
-- <http://caniuse.com> - per-feature tables of support, e.g. to see which engines support modern cryptography functions: <http://caniuse.com/#feat=cryptography>.
-- <https://kangax.github.io/compat-table> - a table with language features and engines that support those or don't support.
+Bu manbalarning barchasi real hayotdagi ishlab chiqishda foydali, chunki ular til tafsilotlari, ularning qo'llab-quvvatlanishi va hokazo haqida qimmatli ma'lumotlarni o'z ichiga oladi.
 
-All these resources are useful in real-life development, as they contain valuable information about language details, their support etc.
-
-Please remember them (or this page) for the cases when you need in-depth information about a particular feature.
