I have this string in javascript.
var X = "<tr><td>pro</td><td>intel</td><td>234</td></tr>"
How can I retrieve the value 234 to another variable from that string?

You've heard the disclaimers about parsing html with regex, but if you want regex, with your input, you can use this pattern:
[^><]+(?=<\/td><\/tr>)
In JS:
var myregex = /[^><]+(?=<\/td><\/tr>)/;
var matchArray = myregex.exec(yourString);
if (matchArray != null) {
thematch = matchArray[0];
}

var x = "<tr><td>pro</td><td>intel</td><td>234</td></tr>";
var res = x.match(/\d+/);
console.log(res[0]);

Try the below regex to get the value inside last <td> tag,
[^<>]*(?=<\/td><\/tr>$)
Code would be,
> var X = "<tr><td>pro</td><td>intel</td><td>234</td></tr>"
undefined
> var out = X.match(/[^<>]*(?=<\/td><\/tr>$)/g);
undefined
> console.log(out[0]);
234

for this string:
var X = "<tr><td>pro</td><td>intel</td><td>234</td></tr>"
.match(/\d+/)[0];
should be sufficient
