lightning-components javascript lightning validation regular-expressions

I have a validation function in lightning component that works on regex. I have a regular expression to check existance of special symbols but I am not able to save my js controller with that regular expression.

Field Integrity Exception: org.auraframework.util.json.JsonStreamReader$JsonStreamParseException: Unterminated string [663, 65]: ';'<>?,./]/;': Source

var regularExpression; 
regularExpression = /[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/; //This line is giving error when trying to save 
if(!regularExpression.test(value)) {
     //Action to be taken
}

The code works fine with some other regex's

Looks like the compiler doesn't like this. Did you try to use the RegExp constructor?

Try using the constructor syntax.

I've verified that this saves in lightning:

var regularExpression; 
var re = new RegExp('[-!$%^&*()_+|~=`{}\[\]:";\'<>?,.\/]');

Note the escape of the ' char within the expression.

Hi Caspar Harmer, thanks for the reply. But the same expression isn't working if passed to RegExp constructor in single quotes.
