Interviews react is not a cup of tea every person, or uphill task. The questions above will take the preparation of a candidate a step further towards achieving their goals. React.js requests increased from day to day and thus competition. The question below will help in preparation for reaction interviews. In addition, this set will guide you through the path of getting the right knowledge on some of the same things.
* What reacts?
* Mention leading features react.
- The reaction feature includes: –
– Utilization of virtual dom instead of real dom.
– Rendering style reaction is a side server.
– Data binding or data flow reacts is Uni – directional.
* Can you count some reaction limitations?
Elements, components and navigation in the user interface are not a cup of tea for beginners and need a little exercise to master or at least understand.
The library is too broad and to find certain tools for the use of someone requires a little experience and some knowledge, tricks and tools obtained.
The use of JSX and Inline templates makes coding with a slightly difficult reaction compared to these tools.
* What exactly is meant by JSX?
* Determine Virtual Dom.
- This is a java script object which is an imitation of the real dom used for lists of elements, objects, attributes and properties. Changes made for them reflect it. But the difference is that only the final change reflects after saving and not a medium unlike real dom.
* Why can’t JSX be read by the browser?
* Distinguish between angles and react.
- The world reacts to have a server side rendering and use virtual dom, angle has client side rendering and using real dom.
* Explain the statement that everything is a component in reacting.
- EVERY UI is divided into component packages. Thus all that is on the reaction is only a component.
* Explain the purpose of rendering ().
- It is used to restore a single representative value of the original DOM component.
* Determine the props.
- Props is the nature of the object stored in reacting.
* Why is the arrow used?
- It is used as a syntax (=>).
* Mention the different phases of the reaction life cycle.
Rendering, update and renewal and unmount phases.
* Mention some life cycle methods.
- comPonent Didmount (), Musta component Update (), Komponend Date (), etc.
* Determine reaction events.
- a reactions are triggered by manual actions such as push buttons, click, etc. Known as an event.
* Set a symbolic event.
- A Cross Browser wrapper around the original browser event.
Thus we can clearly analyze the benefits of the same particular characteristics and estimate enough opportunities for the future. If someone is dedicated enough to build a future with something, he must be able to pass difficult tasks and tasks to be eligible for future benefits. These additional facilities are more helpful in increasing alert responsibilities so that candidates get names and fame in the IT sector as well.
Java is one of the programming languages that are widely used in the industry. There are more than 3 billion devices using Java Script for their software development. A number of employment opportunities are available for Java developers.
