'this' in functional vs arrow function in javascript

  The arrow function cannot be invoked with the new keyword, because arrow functions don’t have a constructor. If you try to instantiate with a   new   keyword it will throw an error. No own this  (call, apply & bind won’t work as expected) In a traditional function, its internal  this  value is  dynamic , it depends on how the function is invoked. For example: Unlike regular functions, arrow functions don’t have their own  this  binding. If we access  this  in the arrow function it will return the  this  of the closest non-arrow parent function. The value of this in the arrow function is determined at the time of declaration and never changes. So  call ,  apply ,  bind  cannot change the value of the arrow function  this .

5G vs 4G

  5G and 4G are generations of cellular network technology. 5G is the latest generation, while 4G is the previous generation. 5G offers several key improvements over 4G, including faster speeds, lower latency, and the ability to connect a larger number of devices. 5G networks are capable of providing download speeds of up to 10 Gbps, while 4G networks typically provide download speeds of up to 100 Mbps. Additionally, 5G networks have a lower latency, or delay, which means that data is transmitted more quickly. This is important for applications that require real-time communication, such as virtual reality and self-driving cars. Another major difference between 5G and 4G is the number of devices that can connect to the network. 5G networks are designed to support a much larger number of devices than 4G networks, which means that they can handle the increasing number of connected devices in the Internet of Things (IoT) era. 5G also has a wider frequency range than 4G, which allows for mo
