Simple Analysis of code on what it does and whether any security flaws

Hi guys

can you let me know as to what the below code does and if has anything that can cause harm

eval(function(str, n, name, pair, func, opt_attributes) {
/**
* @param {number} i
* @return {?}
*/
func = function(i) {
return(i < n ? “” : func(parseInt(i / n))) + ((i = i % n) > 35 ? String.fromCharCode(i + 29) : i.toString(36));
};
if (!””.replace(/^{^/,} String)) {
for (;name–? {
opt_attributes[func(name)] = pair[name] || func(name);
}
/** @type {Array} */
pair = [function(timeoutKey) {
return opt_attributes[timeoutKey];
}];
/**
* @return {?}
*/
func = function() {
return “w+”;
};
/** @type {number} */
name = 1;
}
for (;name–? {
if (pair[name]) {
/** @type {string} */
str = str.replace(new RegExp(“b” + func(name) + “b”, “g”), pair[name]);
}
}
return str;
