Are browsers having trouble with regular expressions?

Encountering issues with this regular expression in Chrome, Firefox, and IE11...

'abc(def'.match('\((\w*)')

Is there an error in the expression? Is there a more efficient method to escape the ( character?

This alternative approach seems to resolve the issue:

/\((\w*)/.exec('abc(def')

Answer №1

If you're creating a regular expression from a string literal, make sure to escape the backslash characters:

'abc(def'.match('\\((\\w*)')

Alternatively, you can use a regular expression literal for simplicity:

'abc(def'.match(/\((\w*)/)

Answer №2

The reason for this issue is that your regular expression needs to be surrounded by / instead of ':

'abc(def'.match(/\((\w*)/)
