Concatenate unicode character (warning sign) with string in javascript

I have a unicode character for warning sign- Unicode Character “⚠” (U+26A0)
https://www.compart.com/en/unicode/U+26A0

I am trying to append this to a string variable but i am not successful in appending the image
Can anyone let me know how to append it here, Also i am trying to make the warning sign yellow in color.

for e.g.
I want the result as -> ⚠ Warning Sign

I tried the following but didnt succeed

let result = `U+26A0` + 'Warning Sign'

>Solution :

You can use the String.fromCharCode(num1) method.

Edit:

That is, String.fromCharCode(0x26A0) + " Warning Sign"
