Take it easy as a javascript if else statement that we use every time whether a condition is true or not.
<pre><code>If(we got success in something){
return resolution of successs;
}else{
return rejection;
}
</code></pre>As above same a Promise can be defined but remember to use new key word while defining it.
<pre><code>const myPromise = new Promise(
(success,failure) =&gt; { if(true){success("resolve");} else {failure("reject");};}
);

const functionToExecutePromise = () =&gt; {
 myPromise
 .then(ok =&gt; {
 console.log(ok)
 })
 .catch(err =&gt; {
 console.error(err)
 })
}

functionToExecutePromise();
</code></pre>
