What are the weaknesses of JavaScript?
Every programming language has its shortcomings and weaknesses. One of the reasons for the problems is the popularity of the language. When a programming language becomes as popular as JavaScript, it becomes a target of increased interest for hackers, scammers, and other malicious third parties who try to find security vulnerabilities and weaknesses.
Some weaknesses:
- Vulnerable to exploits (malicious code that exploits software product vulnerabilities);
- Can be used to run malicious code on the user’s computer;
- Not always supported by some browsers or devices;
- Fragments of JS code may be very large;
- Can display differently on different devices, resulting in a lack of integrity.
