LocaleCompare () lines containing "1" and "-1" in different browsers

Question

I noticed the following differences in return values ​​when comparing strings containing "-1", "1"and "0"using String.prototype.localeCompare()in Chrome and Edge:

"1".localeCompare("-1");
// Edge: -1, Chrome: 1

"0".localeCompare("-1")
// Edge: -1, Chrome: 1

"-1".localeCompare("1")
// Edge: 1, Chrome: -1

• Why is there a difference in return values ​​between browsers?
• Is there a way for browsers to consistently follow in the scripts above?
