What happens if I block javascript?

JavaScript is a scripting language belonging to the network, which has been widely used in Web application development. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect.

JavaScript is used to add dynamic functions to HTML pages. If we block JavaScript, many functions on the page will be unavailable.

JavaScript purpose:

Embed dynamic text in the HTML page. Respond to browser events. Read and write HTML elements. Validate the data before it is submitted to the server. Detect the browser information of the visitor. Control cookies, including creation and modification, etc. Server-side programming based on Node.js technology.

Javascript introduction:

JavaScript (JS for short) is a lightweight, interpretive or just-in-time programming language with function priority. Although it is known as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, multi-paradigm dynamic scripting language, and supports object-oriented, imperative, and declarative (such as functional programming) styles.

JavaScript was first designed and implemented in Netscape Navigator browser by Brendan Eich of Netscape in 1995. Because Netscape works with Sun, Netscape management wants it to look like Java, so it is named JavaScript. But in fact, its grammar style is similar to that of Self and Scheme.

The standard of JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, and older browsers support at least the ECMAScript 3 standard. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, which is officially called ECMAScript 2015, but is often referred to as ECMAScript 6 or ES2015.
