Nullish coalescing javascript operator not working in edge

When I use the ?? javascript operator in Edge, I'm getting a syntax error. For instance, typing the following in the console in Chrome and Firefox works, but it gives a syntax error in Edge.

false ?? 1

Expected result: false

null ?? 1

Expected result: 1

As I said, this works Chrome and Firefox but results in a syntax error in Edge. Any ideas what I'm doing wrong? MDN says Edge supports ??.

Edge Legacy doesn't support Nullish coalescing operator. You could check the MDN Browser compatibility and caniuse. It's only supported by Microsoft Edge version 80+.

If you want to use Nullish coalescing operator in Edge Legacy, you could use Babel to transpile it.

Reference plugin: @babel/plugin-proposal-nullish-coalescing-operator
