Why does backslash get matched on the Unicode U+0060 in Javascript? [closed]

I am wondering why does the Unicode for backtick match on backslash?

In JavaScript this code:

const regex = /[/u0060]/g
const sentence = 'it should match only on this ` not  or /';
console.log(sentence.match(regex));

matches on:

> Array ["`", "/"]

The Unicode character for backslash/ is U+002F and the Unicode character for a backtick or “grave accent” ` is U+0060.

In here it properly distinguishes between the two characters but in JavaScript it seems to not be able to differentiate.
