Promise in Javascript #Node Quick Notes.

Take it easy as a javascript if else statement that we use every time whether a condition is true or not.

If(we got success in something){
return resolution of successs;
}else{
return rejection;
}

As above same a Promise can be defined but remember to use new key word while defining it.

const myPromise = new Promise( (success,failure) => { if(true){success("resolve");} else {failure("reject");};} ); const functionToExecutePromise = () => { myPromise .then(ok => { console.log(ok) }) .catch(err => { console.error(err) }) } functionToExecutePromise();
