Webtrackker is the best React.JS online training in india, To optimally use React, the properties (or accessories), ideally a series of invariable values, are transmitted to the representation function of a component. A component can not directly modify the attributes passed to the component, but must pass callback functions that modify the store and create a unique source of truth. The promise of this mechanism is expressed as "the properties flow down, the actions flow upwards". The mechanism described is an architecture called Flux. [11] [12] Many Flux alternatives have been made since the beginning, but the community has gone in the direction of Another remarkable feature is the use of a 'virtual object model for documents' or 'virtual DOMs'. React creates a data structure cache in memory, calculates the resulting differences and then efficiently updates the displayed DOM of the browser. [14] This allows the programmer to write the code as if the entire page were processed with each change, while the React libraries represent only the subcomponents that actually change. Responsiveness components are usually written in JSX, a syntax of the JavaScript extension that allows HTML to be cited, and HTML tags can be used to display the subcomponents. [15] This is a React-specific grammar extension for JavaScript, like the now-defunct E4X. The HTML syntax is processed in JavaScript calls to the React frame. Developers can also write in pure JavaScript. JSX is similar to another extension syntax created by Facebook for PHP, XHP. JSX looks like normal HTML. An example of JSX code: multiple elements must be packaged in a single container element as the <div> element shown above. From React v16.0 it is now possible to return an array of elements, fragments and strings. Custom attributes are compatible along with HTML attributes. Custom attributes must be added to the data type. The custom attributes of v16.0 are now passed
