If you really want a safe map where any key is allowed and doesn't conflict
with builtin javascript properties, just implement your own map. Here is a
very simple one that allows storing *any* value as keys. This includes the
string "__proto__" as well as non-strings.
If you want something faster and your pretty sure that "__proto__" will
never be used as a key and all other keys are strings, then use native
objects with Object.create(null). Mostly safe is good enough for a large
number of cases. Including generating prime numbers for RSA private keys
for your online bank.
function map() {
var keys = [];
var values = [];
return { get: get, set: set };
function get(key) {
return values[keys.indexOf(key)];
}
function set(key, value) {
var index = keys.indexOf(key);
if (index < 0) {
index = keys.length;
keys[index] = key;
}
return values[index] = value;
}
}
