Hi, how are you? I like the work you do and the videos you publish. I don't have a professional profile, I don't have a CS degree, I don't even have full secondary education. What course do you recommend to me, that can gives me the knowledge and solid foundations to start as a confident front end web dev and that gives me the possibility to start practicing and carry out my own projects, my idea is to be able to reconvert myself and in the future get a job in the field, I hope you can help me, thanks

@saddamansari5223 2 года назад

Thanks but i have one question, how do we know the promise gets resolved or reject now we just assume that the promise is resolved so can you please understand me

@ThapaTechnical Год назад

You can use an if-else statement to determine whether to return a resolved or rejected Promise. Here is an example: function myPromiseFunction(someCondition) { if (someCondition) { return Promise.resolve("Success!"); } else { return Promise.reject("Error!"); } }

@sarojinirout758 2 года назад

If u won't find resolve, then why will u use then... Instead of then u can write only catch for reject

@AshishGautam-sy3vm 2 года назад

great

@subhamgupta2211 2 года назад

Can I declear resolve and reject in one function??? Please reply

@ThapaTechnical Год назад

Yes, it is possible to declare both a resolved and rejected state in a single function. You can use an if-else statement to determine whether to return a resolved or rejected Promise. Here is an example: `function myPromiseFunction(someCondition) { if (someCondition) { return Promise.resolve("Success!"); } else { return Promise.reject("Error!"); } }`

@sbo-world 3 года назад

please help thapa sir, 1st condition false hone pe direct catch(error) section me chala jaa raha hai or second function jo hmne created kiya hai wo run hone nhi de raha hai ..... why ? please explain . //exicutor // promise produce const obj1 = new Promise((resolve, reject)=>{ setTimeout(()=>{ let rollnum = [1,2,3,4,5]; let i=2; if( i==1){ resolve(rollnum); }else { reject("Communication error is coming please check your connection"); } },2000); const getBiodata = (rollno) =>{ return new Promise((resolve,reject)=>{ setTimeout((rollno)=>{ const details = { name:'shabbo', age:25 } resolve(`My roll number is ${rollno}. My name is ${details.name} and I'm ${details.age} years old`); },2000,rollno); }) } }); obj1.then((rollno)=>{ console.log(rollno); return getBiodata(rollno[1]); }).then((rollno)=>{ console.log(rollno); }).catch((error)=>{ console.log(error); });
