Does JavaScript take local decimal separators into account?

Question

I\'ve got a web page that displays decimals in a user\'s localized format, like so:

• English: 7.75
• Dutch: 7,75

Answer 1

No, comma (,) is an operator having special meaning, just like dot (.). Otherwise things as simple as:

var array1 = [1,2];
var array2 = [1.2];

would break under different locales. All mainstream languages I know treat . and , separately and stricly, irrespective to locale.
