    Rule Details

    Disallows octal escape sequences in string literals.

    As of the ECMAScript 5 specification, octal escape sequences in string literals are deprecated and should not be used. Unicode escape sequences should be used instead.

    Examples of incorrect code for this rule:

    var foo = 'Copyright \251';
var foo = '\1';
var foo = '\01';
var foo = '\08';

    Examples of correct code for this rule:

    var foo = 'Copyright \u00A9';
var foo = '\x51';
var foo = '\0';
var foo = '\\1';
