I wanna basically execute a statement stored in a var. For example, I have this,

var statement = "alert('Hi!')";

How can I make JS execute the statement stored inside the var statement? Thanks a lot guys.

This will do it, but it's not recommended

var statement = "alert('Hi!')";
eval(statement)

It does not even work. Any other solution?

You could use Function constructor

var func = new Function("alert('Hi!')")
func(); // call it

You could eval but this method is comparatively safer.

You're probably looking for eval
var test = "alert('toto')";
eval(test);

you can use eval("my script").

You should be able to use eval() like this: 

var statement = 'alert('Hi!');";
eval(statement);

eval is a dangerous thing though and should be used with caution.
