Essential Computer Glossary for JavaScript Developers

This resource provides definitions and explanations of key computer and programming terms relevant to JavaScript and web development. Understanding these terms is crucial for beginners aiming to enhance their programming skills.

Key Concepts

1. Algorithm

• Definition: A step-by-step procedure for solving a problem or completing a task.
• Example: A recipe for baking a cake.

2. API (Application Programming Interface)

• Definition: A set of rules that allows different software applications to communicate with each other.
• Example: Using a weather API to fetch weather data for a specific location.

3. Array

• Definition: A collection of items stored at contiguous memory locations, used to store multiple values in a single variable.
• Example: let fruits = ['Apple', 'Banana', 'Cherry'];

4. Boolean

• Definition: A data type that can hold one of two values: true or false.
• Example: let isAvailable = true;

5. Function

• Definition: A block of code designed to perform a particular task, which can be called upon whenever needed.
• Example: function greet(name) { return 'Hello ' + name; }

6. Object

• Definition: A collection of properties, where each property is a key-value pair.
• Example: let person = { name: 'John', age: 30 };

7. Variable

• Definition: A named storage location in memory that can hold data.
• Example: let age = 25;

8. Loop

• Definition: A programming structure that repeats a sequence of instructions until a specific condition is met.
• Example: for (let i = 0; i < 5; i++) { console.log(i); }

Importance for Beginners

• Foundation of Programming: These terms form the basic vocabulary necessary to understand programming concepts.
