I need regex for replace words inside text and not part of the words.
My code that replace 'de' also when it’s part of the word:
str=de degree deep de;
output=str.replace(new RegExp('de','g'),'');
output== gree ep
Output that I need: degree deep
What should be regex for get proper output?
str.replace(/bdeb/g, '');
Note that
RegExp('\bde\b','g') // regex object constructor (takes a string as input)
and
/bdeb/g // regex literal notation, does not require escaping
are the same thing.
The b denotes a word boundary. A word boundary is defined as a position where a word character follows a non-word character, or vice versa. A word character is defined as [a-zA-Z0-9_] in JavaScript.
Start-of-string and end-of-string positions can be word boundaries as well, as long as they are followed or preceded by a word character, respectively.
Be aware that the notion of a word character does not work very well outside the realm of the English language.
