javascript - Find words from array in string, whole words only (with hebrew characters)

Question

I have to build a RegExp obejct, that will search words from an array, and will find only whole words match.

e.g. I have a words array ('??','???'), and I want the RegExp to find 'a' or '??' or '???', but not '????'.

This is my code:

var text = '??? ????? ??';
var matchWords = ['??','???'];
text = text.replace(/
$/g, '

').replace(new RegExp('\b(' + matchWords.join('|') + ')\b','g'), '<mark>$&</mark>');
console.log(text);

Answer 1

The word boundary is not Unicode aware. Use XRegExp to build a Unicode word boundary:

var text = '??? ????? ??';
var matchWords = ['??','???'];
re = XRegExp('(^|[^_0-9\pL])(' + matchWords.join('|') + ')(?![_0-9\pL])','ig');
text = XRegExp.replace(text.replace(/
$/g, '

'), re, '$1<mark>$2</mark>');
console.log(text);
