The new function cannot reference the local variables of the outer function. When you use new Function(…) (the Function constructor) inside a function, it does not close over its lexical environment: it closes over the global context instead.
The text you eval can reference local variables of the function, and in the non-strict mode, you can even create new local variables by using eval('var foo = …'). Whenever you use eval() inside a function, a closure is used.Returning a function from inside another function is the classic example of closure, because the state inside the outer function is implicitly available to the returned inner function, even after the outer function has completed execution.Whenever a function is declared in JavaScript closure is created.The following will print `3`, three times.
Const secret = unc(Math.random()*100)Ĭonsole.log(`The secret number is $ )
