آموزش پروژه محور جاوا اسکریپت - Capturing and Bubbling
در قسمت ششم از آموزش پروژه محور جاوا اسکریپت به بررسی مفهوم Capturing and Bubbling در مدیریت Event ها پرداختیم. ابتدا به بررسی رویکرد مرورگر برای مدیریت Event در فازهای Capturing و Bubbling پرداختیم و سپس شیوه اضافه کردن Event Listener برای هر کدام از فازها را شرح و در نهایت یک مثال ساده از کاربرد آن را بررسی کردیم. در خاتمه یک کوییز و سوال کوچک جاوا اسکریپتی رو مطرح کردم :)

Telegram is a cloud-based instant messaging service that has been making rounds as a popular option for those who wish to keep their messages secure. Telegram boasts a collection of different features, but it’s best known for its ability to secure messages and media by encrypting them during transit; this prevents third-parties from snooping on messages easily. Let’s take a look at what Telegram can do and why you might want to use it.
Telegram and Signal Havens for Right-Wing Extremists
Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
