Lessons Learned

Regex for multiple text

replace(/\b(?:this|that|there|those)\b/gi, '')

• /.../: standard Regex syntax
• \b: assert position at a word boundary; prevents partial match; exact match
• (text1|text2): match with parameter 'this', 'that' and so on
• |: or conditional; note that the text should be near this
• g modifier: global match
• i modifier: case-insensitive match

const text = 'This soup from that store was made over there with those vegetables'
(text.replace(/\b(?:this|that|there|those)\b/gi, '').trim()
> 'soup from  store was made over  with  vegetables'
