Javascript date method toISOString doesn't return proper date-CodePudding

I had an issue with Date:

I want to get the last day of month

const date = new Date();
const lastDayOfMonth = new Date(date.getFullYear(), date.getMonth()   1, 0);
console.log(lastDayOfMonth); //Wed Nov 30 2022 00:00:00 GMT 0000 (temps universel coordonné)
console.log(lastDayOfMonth.toISOString()) //2022-11-30T00:00:00.000Z

The same code I've run on other computer's browser I found the same result except console.log(lastDayOfMonth.toISOString()) //2022-11-29T00:00:00.000Z, I got 29 instead of 30?

I don't know why? if anyone knows, could explain us more why Date behave differently on different browser...

CodePudding user response：

var date = new Date(); 
date.setMonth(date.getMonth() 1); 
date.setDate(0);

The setDate with 0 gives back the previous month day

const date = new Date();
const lastDayOfMonth = new Date(date.getFullYear(), date.getMonth()   1, 0);
console.log(lastDayOfMonth); //Wed Nov 30 2022 00:00:00 GMT 0000 (temps universel coordonné)
console.log(lastDayOfMonth.toISOString()) //2022-11-30T00:00:00.000Z
