JavaScript

JavaScript, language of the web,is one of triad of the languages along with HTML and CSS that defines web.
It is the most widely misinterpreted language in the existence.
First of all, it is in no way related to Java except the name.
Every dynamic feature of the web is developed by JavaScript like search suggestions in the browser,
location of information, every update that happens without user intervention.


Much of its syntax is derived from self,a dynamic language.
Because of its expressiveness, this language just intended to be a scripting language because of the  explosion of the web increased its potential to that of a general programming language.
Certain implementations of the language have caused the vulnerabilities and threats which include eval() function which is executed at the run time making the static analysis all the more difficult.
Douglas Crockford, senior JavaScript programmer at Yahoo and developer of JSLint and JSON felt that certain that Certain JavaScript features' usage should be avoided as the security threats they pose are incomparable to the features they present.
