Abstract:

The technical description and instruction is an instructional guide to using a technical device. My technical description and instruction is on the use of JavaScript, a programming language. In the technical description, I overview what JavaScript is, its purpose, how it functions, it’s principle parts, and how its parts work together. The paper instructs readers on how to navigate through JavaScript and use it accurately in order to create codes and programs.

JavaScript Technical Instructions

Definition:

A computer programming language.

Purpose:

JavaScript is used to code for and develop web-based applications, web browsers, software, servers, and embedded hardware controls.

Overview:

A series of statements and codes listed in chronological order on a black or white background. Expressions, keywords, and symbols are colored differently to highlight distinct statements.

How it Works:

JavaScript contains a list of programming statements, which are a set of values, operators, expressions, keywords, and comments used to communicate instructions to a computer and/or software. JavaScript allows users to use programming statements to give the computer instructions to execute.

Principle Parts of Coding:

Statements:

• There are many statements in JavaScript. Each statement gives a distinct instruction. Statements are written one by one and are executed in the order in which they are written.

Semicolons;

• Semicolons are used to end JavasScript statements. Individual statements are identified and executed by the computer, based on the placement of semicolons.

Code Blocks:

• Code blocks are statements grouped together using curly brackets, {…}, to be executed together. These code blocks are used to define new single statements that incorporate multiple instructions.

Conclusion:

The various tools and devices in JavaScript can be used together to create instructions for computers to develop specific programs, software or applications that users want to make. Statements, semicolons, and code blocks work simultaneously to create codes that computers execute on. For example, this is a calculator created through JavaScript using statements, semicolons, and code blocks:
