return reject has no special meaning. Promise makes Promise complete or failed through resolve and reject . Your return reject ('2') is executed reject ('2') and pops out.
if you return in advance, it will cause the Promise to be pending state.

new Promise((res,rej)=>{
res();
console.log(1);
rej();
console.log(2)
