Javascript newdate function unexpected output

I am confused by the result of the following script and I don't understand why it is what it is:

enddate = '01-02-2020'; //euro format dd-mm-yyyy
datesplit = enddate.split("-"); 

console.log("datesplit: ", datesplit); //[ '01', '02', '2020' ]
console.log(datesplit[2]); // 2020
console.log(datesplit[1]); // 02
console.log(datesplit[0]); // 01

enddate1 = new Date(datesplit[2],datesplit[1],datesplit[0]);

console.log("enddate 1", enddate1); //output: 2020-03-01T05:00:00.000Z , but I'm expecting 2020-02-01T00:00:00.000Z

That last console log output is what I can't understand. I would appreciate an explanation of why the result is what it is.
