Is there any way to modify variables accessed using closures and have no way to access them
I just now saw an example of closures in Javascript MDN website. Which is this:
var getCode = (function()
var apiCode = '0]Eal(eh&2'; // A code we do not want outsiders to be able to modify...
return function()
return apiCode;
;
)();
console.log(getCode()); // Returns the apiCode
I'm a beginner and I want to know Is apiCode variable in the code completely unaccessible. Or if there is any way to modify its value

It's only accessible from within the getCode method.

There is NO WAY to protect code that is available on the browser. Set a breakpoint and change the variable. TADA. Override the function from the console, set it to whatever you want. Hijack the http request with a proxy, alter it anyway you want.

@Adriani6 Does it mean that it is unaccessible without changing the code?

@Hemanbabu Yes. That's the point of a closure. But note what the 2nd comment said. That's fundamentals of client-side development. It all depends on what you mean by accessing the variable. Programatically? Then you're good, anything else you're not good.

It is protected in a sense that noone can modify it, but everyone can see it, that is for sure.
