Right way to declare a static Javascript map with String keys and String values

Question

Is this the right way to declare a static Javascript map of String keys and String values?

var myMap = {
    "key 1" : "value 1", 
    "key 2" : "value 2", 
    ...
    "key n" : "value n"
};

REM: all keys and values will be html escaped for special characters, they may contain blank spaces.

Yes, that's the normal and correct way to initialize a Javascript object.

Prasath, how is this not a real question? Where do you get that from SO guidelines and FAQs? – Jérôme Verstrynge Apr 11 '13 at 10:59

That's a fine object literal, yes. Though, there is nothing really "static" in JavaScript (only the scope of the myMap variable which you declared with var, but not it's value).

all keys and values will be html escaped for special characters

That sounds unnecessary, unless you expect the strings to be written into html markup (and there are better ways). If you just escaped them since the script is included in a html document, it was useless - the only thing that needs to be escaped in inline scripts is the sequence </script>. You just have to string-escape them (i.e. escape backslashes and quotes).

How? If you properly use `document.createTextNode`, you don't need to escape them. Only if you do something like `"
"+key+myMap[key]+"
"` you need to worry about escaping (and injections). — Bergi, Apr 11 '13 at 11:03
