How to write special characters in template literals?

I am using template literals for a string in javascript and want to insert special characters like & and $ with hex code (&lettersandnumbers;) like you would in normal strings but it doesn't read it. I tried putting it in ${} but that didn't help either. Is there a way to write it?

The &lettersandnumbers; escape sequence is for HTML, not JavaScript strings. In javascript strings, there are different ways to represent a special character. In your case, you do not need to escape the character "$" or "&".

To represent a character in a string with a hexadecimal code, do this:`I like \x24\x24\x24!` which evaluates to "I like $$$!".

See Escape notation on MDN:

Code Output
\0 U+0000 NULL character
' single quote
" double quote
\ backslash
\n new line
\r carriage return
\v vertical tab
\t tab
\b backspace
\f form feed
\uXXXX (where XXXX is 4 hex digits; range of 0x0000–0xFFFF) UTF-16 code unit / Unicode code point between U+0000 and U+FFFF
\u{X} ... \u{XXXXXX} (where X…XXXXXX is 1–6 hex digits; range of 0x0–0x10FFFF) UTF-32 code unit / Unicode code point between U+0000 and U+10FFFF
\xXX (where XX is 2 hex digits; range of 0x00–0xFF) ISO-8859-1 character / Unicode code point between U+0000 and U+00FF

You can use escape character (backslash - \) to treat special characters as normal ones.

const text = `text\$somemoretext\&end`;
console.log(text);
