How to show the emoji symobol using javascript?

Answer 1

You could use the regex /&# (\\w+);/ to get each Code point to a capturing group. Then use String.fromCodePoint method in the replacement function of replace to get the emojis like this:

 const str = '&# 128079;&# 128079;&# 128079;&# 128079;' const emojiStr = str.replace(/&# (\\w+);/g, (m, c1) => String.fromCodePoint(c1)) console.log(emojiStr) 

( Regex demo )

If you just want to display it on the DOM, you can just remove the space ( \\s ) and set the escaped string to innerHTML

 const str = '&# 128079;&# 128079;&# 128079;&# 128079;' document.getElementById('display').innerHTML += str.replace(/\\s/g, '') 

 <span id='display'></span>
