An HTML page is a static one and without JavaScript it would be static still. JavaScript can make the website more interactive and user- friendliness of JavaScript helps easy navigation of the website and helps designers to guide the visitors with additional information or guide them through walkthroughs.

Advantages of JavaScript Client-side JavaScript is very fast because it can be run immediately within the client-side browser. Unless outside resources are required, JavaScript is unhindered by network calls to a backend server. Simplicity. JavaScript is relatively simple to learn and implement.

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user.

Modern JavaScript is a “safe” programming language. It does not provide low-level access to memory or CPU, because it was initially created for browsers which do not require it. js supports functions that allow JavaScript to read/write arbitrary files, perform network requests, etc.

JavaScript can be dangerous if the proper precautions aren’t taken. It can be used to view or steal personal data even you don’t realize what’s going on. And since JavaScript is so ubiquitous across the web, we’re all vulnerable.

The most secure language, ColdFusion, had six vulnerabilities per slot. Perl had seven vulnerabilities per slot and PHP had 10. While 31 percent of all vulnerabilities were in . NET, the report noted that there were more websites written in .

Ruby

Programming languages, like C and C++, use pointer values to manage application memory and safeguard data. Java, on the other hand, uses its own internal memory and data management systems to block any unauthorized data access. These systems are much more difficult to infiltrate.

Here’s what the company found: The most insecure languages are C, Java, JavaScript, Python, Ruby, PHP, and C++. This is not to say that C is less secure than the other languages. The high number of open source vulnerabilities in C can be explained by several factors.

The top vulnerabilities found in C were buffer errors and input validation, the report reads, and although numbers have both risen and fallen since 2009, it remains the most insecure language. In C’s defense, it should be noted that this is the oldest (and most widely used) programming language in the list.
