How do you find Korean letters using regex in JavaScript?

回答1:

You can use the following regex

const re = /[\u3131-\uD79D]/ugi

This is the code table that I referenced: http://memory.loc.gov/diglib/codetables/9.3.html

Try it yourself:

const re = /[\u3131-\uD79D]/ugi
console.log("abcde".match(re)) // null
console.log("안녕".match(re)) // ["안", "녕"]
