Why you should care

[/vc_column_text][vc_column_text]Continuing a string across a linebreak is supported in most script engines, but it is not a part of ECMAScript. Additionally, the whitespace at the beginning of each line can’t be safely stripped at compile time, and any whitespace after the slash will result in tricky errors.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time a multiline string is encountered, that is a string containing newline preceded by “\”.

Bad Code 

var myString = 'A rather long string of English text, an error message \
actually that just keeps going and going -- an error \
message to make the Energizer bunny blush (right through \
those Schwarzenegger shades)! Where was I? Oh yes, \
you\'ve got an error and all the extraneous whitespace is \
just gravy. Have a nice day.'; // Noncompliant

Good Code 

var myString = 'A rather long string of English text, an error message ' +
'actually that just keeps going and going -- an error ' +
'message to make the Energizer bunny blush (right through ' +
'those Schwarzenegger shades)! Where was I? Oh yes, ' +
'you\'ve got an error and all the extraneous whitespace is ' +
'just gravy. Have a nice day.';
