a lot of people hate on javascript for like things that are just part of the ieee754 floating point standard, and not for the actual bad things about the language, like how the array 'sort' method casts numbers to strings and sorts them lexicographically, or how typeof null === 'object' when null is actually a primitive value of type null

Google подтвердил, что теперь для отправки запросов в их поисковик обязательно нужно использовать JavaScript. Компания объясняет, что это нововведение повысит безопасность Google Search, защищая его от ботов, спама и попыток манипуляции алгоритмами SEO. Хотя JavaScript — это один из самых популярных языков программирования для веб-приложений, его всё ещё избегают некоторые пользователи. Но теперь Google заставляет эту небольшую группу использовать язык, совместимый с ECMAScript, для поиска в интернете. JavaScript появился в первые годы развития интернета, когда Netscape и Sun Microsystems начали работать вместе, чтобы добавить язык программирования в браузер Navigator. Сейчас торговая марка "JavaScript" является частью судебного разбирательства между Oracle и сообществом JS, но язык всё равно остаётся ключевым для работы современных интерактивных сайтов и браузеров. Google уверяет, что с этим изменением поиск станет работать быстрее и эффективнее, а без включённого JavaScript он просто не будет нормально функционировать. Боты, спам и другие способы манипуляции алгоритмами постоянно развиваются, и поэтому для обеспечения безопасности и лучшего обслуживания пользователей Google использует возможности JavaScript на полную катушку. Некоторые пользователи по-прежнему избегают использования JavaScript по соображениям конфиденциальности или для повышения безопасности в очень чувствительных онлайн-средах. JavaScript действительно может увеличить поверхность для атак со стороны киберпреступников и враждебных стран, при этом крупные разработчики браузеров исправляют уязвимости с высокой или критической опасностью каждую неделю. Google сообщает, что количество поисковых запросов, обслуживаемых без использования JavaScript, составляет менее 0,1 процента от общего числа. Поскольку Google Search обрабатывает около 8,5 миллиардов запросов каждый день, эта маленькая группа пользователей всё равно составляет миллионы людей, которые ищут информацию в интернете без включенного JavaScript. Некоторые пользователи всё ещё избегают JavaScript из соображений конфиденциальности или чтобы повысить безопасность в очень чувствительных интернет-средах. Действительно, использование JavaScript может увеличить риски атак со стороны киберпреступников и враждебных государств, поскольку крупные разработчики браузеров ежемесячно исправляют серьёзные уязвимости в безопасности. Google сообщает, что поисковые запросы без JavaScript составляют менее 0,1% от общего числа. Учитывая, что Google Search обрабатывает около 8,5 миллиардов запросов каждый день, это всё равно означает, что миллионы пользователей продолжают искать информацию в интернете, не включая JavaScript. Новое требование по использованию JavaScript может не только создать угрозу безопасности для некоторых пользователей, но и негативно повлиять на сторонние инструменты для проверки позиций сайтов в Google Search. Недавний отчет Search Engine Roundtable сообщил, что несколько таких инструментов перестали работать после того, как Google ввел обязательное использование JavaScript. Компания не прокомментировала этот отчет, хотя поисковая система, которая меньше ориентируется на SEO, могла бы стать полезным улучшением для по��ьзователей, работающих в интернете.

Difference between ES5 and ES6

JavaScript is the must need programming language for both web and software engineering, and it keeps on changing with time. All developers should know the difference between ES5 and ES6 because major variations and advancements were made in those versions. ES5 started the foundation and had shown more advanced features in the version of ECMAScript 2015, also known as ES6. At TCCI Computer Coaching Institute, we ensure that each student understands these updates deeply so that they can be ahead in their programming journey.

What is ES5?

ES5, which stands for ECMAScript 5, was launched in 2009. This is the version of JavaScript which was seen to be stable, and it filled some of the most important holes that were there in the earlier versions. Key features of ES5 include:

Strict Mode: Strict mode allows developers to write secure and optimized code because it throws an error for all actions that are allowed in other versions.

JSON Support: ES5 provided support to work with JSON (JavaScript Object Notation), which is an essential feature for data interchange.

Array Methods: It introduced several new array methods, such as forEach(), map(), filter(), and reduce(), that simplify operations on arrays.

Getter/Setter Methods: ES5 allows the use of getter and setter methods, making it possible to control object properties.

What is ES6?

ES6, also commonly referred to as ECMAScript 2015, was a substantial update to the JavaScript language to include many new features as well as additions that make this language more powerful, concise, and much more modern in its expression. Some of its key features include:

Let and Const: There are let and const, added to declare a variable, with let offering better scoping than var, and const having no redefinition.

Arrow Functions: More concise syntax - also preserves this context.

Template Literals: Template literals ease string interpolation and multiline strings, and are much readable and less error-prone.

Classes: Classes, which are new in ES6, make the syntax for creating objects and handling inheritance much simpler than it used to be. It makes JavaScript resemble other more conventional object-oriented programming languages.

Promises: The promise is how asynchronous code works; promises handle success and failure states much easier.

Destructuring: This helps extract values from arrays and objects into separate variables in a simple syntax.

Modules: ES6 provided modules, where JavaScript code could be broken into reusable, maintainable pieces.

Key differences between ES5 and ES6

Variable declarations:

ES5 : Variables are declared using var.

ES6 : let and const keywords were introduced which provide block scoping and better predictability

Functions:

ES5: The function keyword is used to declare functions, and the this context can be a little tricky in some cases.

ES6: Arrow functions offer a more compact syntax and lexically bind the this keyword, avoiding common problems with this.

Object-Oriented Programming:

ES5: JavaScript uses prototype-based inheritance.

ES6: Introduces the class syntax, making object-oriented programming much more intuitive and easier to use.

Asynchronous Programming:

ES5: Callbacks are typically used for handling asynchronous code.

ES6: It introduced promises that made asynchronous operation cleaner.

Modules:

ES5 JavaScript does not natively support modules. Developers will use libraries such as CommonJS or RequireJS.

ES6 Native module support using the keywords import and export, which facilitates code organization and reusability

Template Literals:

ES5 String concatenation is done by using + operators, which can sometimes be error-prone and messy to read.

ES6 Template literals enable multi-line strings and interpolation of strings, enhancing readability.

Why Is It Important to Learn ES6?

At TCCI Computer Coaching Institute, we understand that staying updated with the latest advancements in JavaScript is crucial for your programming career. Learning ES6 is not just about getting familiar with new syntax, but also about adopting best practices that improve the quality and maintainability of your code.
