All the conditions required to reach RHCE can be found on the Red Hat website. Unlike Microsoft and CompTIA certification, you cannot find the Red Hat Test message in any VUE or Prometric test center. Red Hat performs tests much like Cisco's CCIE Certification. You must go to the test center specified by the manufacturer to take the tests. Of course, this measure alone compares few Linux certification vendors.
How to prepare for the RHCE cert

8. js implements a simple calculator
This is a js-based calculator applet. The calculator features very simple functions and can implement simple addition, subtraction, multiplication, division operations. Although it is very simple, the calculator looks pretty good. In addition, you can also implement more advanced computing functions by yourself. After all, you can use Javascript to implement all mathematical operations.

Riot. js is a client Model-View-rendering (MVP) framework and is very lightweight or even smaller than 1kb. despite its incredible size, all it can build are as follows: a template engine, a route, even a library and a strict and organized MVP model. The view is automatically updated when model data changes.
Of course, in addition to the above mentioned, there are many excellent Javascript frameworks and libraries, and a new produ
