Question

I have this line in my Javascript code:

var regex = /===Hello===\n/;

JsHint gives me a warning in this line:

A regular expression literal can be confused with '/='`

…but I don’t know what’s wrong with this regular expression? How can I avoid this warning?

Answer 1

The problem is that /= could be interpreted as a division and assignment, rather than the start of a regular expression literal.

You can avoid the warning by using the RegExp constructor instead:

var regex = new RegExp("===Hello===\n");

There doesn’t appear to be any option you can set to tell JSHint (or JSLint for that matter) to ignore /=, so your choice is either to work around it or ignore the warning.
