Is Java script safe? For what javascript is used for?

JavaScript is “relatively safe,” but not “absolutely safe.” Any program you run on your computer has the potential to do damage.

There is no absolutely secure system, except for the one that was never used. JavaScript language is more securer than placing an anonymous USB device in your computer.

And safer than a binary you download from an untrustworthy website or get in a suspect email attachment. It is much more securer than some of the scripts you’ll find on websites that tell you to copy-paste them into your shell.

In general, it is not absolutely safe. Bugs in the browser’s operate time engine, the browser itself, the anti-virus, or even the processor itself can all compromise JavaScript’s security.

The system is only as secure as its weakest security. The security of JavaScript is mostly meant to prevent “casual” exploits (such as an 8-year-old learning JavaScript for the first time and accidentally writing an exploit).

Actually it doesn’t stand a chance against dedicated attackers. JavaScript is complicated enough that there are bound to be bugs, perhaps in unexpected ways.

Those observed in hacking, pen testing, and security can. Browse through source code, debug executables.

You can do anything else they can to try and find chinks in the armor.

The low areas of the JavaScript implementation. And JavaScript is great enough that such chinks exist to start with, since it is actually impossible to even automate all the probabilities that would find these bugs.

However, once you begin going off the beaten path. It is actually likely you will get your system exploited at few point if there is even a single weak point. It only takes one really good exploit, or two or three in tandem, to fully take over a system.

Hope by this you understand is java script safe?

For waht java script is used for?

JavaScript is a text-based coding language utilized both on the client-side and server-side that permits you to make web pages presentable. Where HTML and CSS are languages that give structure and style to web pages, JavaScript provides web pages good elements that engage a user.
