You can do this with regex:

var mystring = "<!-- html-text: 143 --> value 1  <!-- /html-text --><!-- html-text: 144 --> | <!-- /html-text --><!-- react-text: 145 --> value 3 <!-- /html-text --><!-- html-text: 146 -->, <!-- /html-text --><!-- html-text: 147 --> value 2 <!-- /html-text --><!-- html-text: 148 --> <!-- /html-text --><!-- html-text: 149 -->value 4 <!-- /html-text -->";
mystring = mystring.replace(/<!--.*?-->/g,'');

console.log(mystring);

Regex explanation:

  1. <!--...--> Marks the opening and ending of an HTML comment
  2. .* Matches any character zero or more times
  3. ? Remove "greedy matching" (match the least possible instead of most)
  4. g Global, meaning to replace all occurrences instead of just one
