How to write if statement in React.js?




How to write if statement in React.js?

Obviously, in the event that we consider if proclamation in Javascript or Typescript rationale, it's equivalent to in each Javascript or Typescript place. 

It's simply if/else like unadulterated javascript, however for this situation, we won't talk about the typical if/else. 

In respond, we'll need if proclamations for the one more thing, it's the delivering. 

It's named "Contingent delivering", however to make it basic, how about we remain with "if proclamation in respond". 

There are the two most mainstream approaches to utilize restrictive delivering that we'll find in the React.js code, and relies upon a case, them two are right. 

The main way that we can utilize is to characterize the contingent delivering legitimately in the segments format. 

It's brisk and simple that we'll utilize the most, and now and again, it is the best for execution. 

We'll be utilizing along these lines in the situations when we have just one condition, all the more similarly as "if", when we might want to deliver some component when a predefined condition is passed. 

The subsequent way is the capacity made to deal with indicated portions of the design, and render it restrictively, to do that we can utilize if/else however the switch case too. 

This single direction is on the whole correct to use in situations where we have more conditions, particularly the form with switch one. 

Be that as it may, it fires the capacity in any case, so it is no sense to utilize it when we have one condition. 

We should investigate the code models where I included the two different ways of doing that:

// The first example with the code inside functional component
function Parent(props) {
  return(
    <>
      {name === "CrowdforThink" && (
        <CrowdforThinkComponent/> 
      )}
    </>
  )
}

// The second example with the additional function
function renderComponent() {
  const name = 'CrowdforThink';
  if (name === 'CrowdforThink') {
    return 'CrowdforThink';
  } else {
    return null;
  }
}

function Parent(props) {
  return renderComponent();
}
