💻 Systematic Go Learning & Development

Structured Go language learning environment documenting core progression from syntax → data structures → control flow → structs & methods → CLI tooling. Built over 30+ exercises with full operational logs, screenshots, and debugging documentation to reinforce reproducible, verifiable growth.

🧠 Focus: Go fundamentals for IaC & platform automation · 🪵 30+ logged troubleshooting events · ⚙️ Verified reproducible execution

🚀 Project Overview

This repository documents a dedicated, systematic learning initiative for Go, with a focus on core concepts essential for modern Platform Engineering and Infrastructure as Code (IaC). The goal is to build the knowledge necessary for developing high-performance, concurrent, and scalable systems tools (CLI utilities (current) Microservices in progress).

📚 Core Learning Concepts by Category

The following sections organize the learning artifacts by logical concept, demonstrating progression from basic syntax to data structure manipulation.

1. Variables, Types, and I/O Fundamentals

Date	File	Concept & Documentation
2025-09-04	goodEvening.go, greeting.go	Basic package declaration and I/O using fmt.Print/Println. Includes initial troubleshooting/debugging on comment syntax (# vs //).
2025-09-06	nameLocationOpinion*.go	Demonstrates variable assignment, string interpolation, and I/O formatting (newline characters and fmt.Println).
2025-09-07	shorthand.go	Usage of shorthand declaration (:=) for implicit type inference.
2025-09-11	outerInnerBlocks.go	Exploration of variable scope and shadowing in outer and inner code blocks.
2025-09-11	zeroValues.go	Demonstrates default zero values for various data types (string, int, bool).
2025-09-14	dataTypes.go	Explicitly verifies variable types using the reflect.TypeOf function.
2025-09-14	intToFloat64.go, float64ToInt.go	Demonstrates explicit type casting between numeric types.
2025-09-14	strIntAtoi.go, strToIntErr.go	Uses strconv.Atoi for string-to-integer conversion, including structured error handling and intentionally triggering errors to demonstrate error flow.
2025-09-14	constants.go, constantsError.go	Defines typed and untyped constants, including demonstrating compile-time errors with mismatched constant types.

2. Operators and Control Flow

Date	File	Concept & Documentation
2025-09-17	comparisonOperators.go	Usage of all six comparison operators (==, !=, >, <, >=, <=) to return boolean values.
2025-09-20	arithmeticOperators.go	Execution of basic mathematical operations (+, -, *, /, %).
2025-09-26	logicalOperators.go	Demonstrates logical operators (AND &&, OR `
2025-09-26	assignmentOperators.go, bitwise_operators.go	Demonstrates all five assignment and bitwise operators.
2025-09-28	ifElseStatements.go	Implements conditional logic using if-else blocks. Includes troubleshooting on incorrect shorthand usage.
2025-09-28	switchCase.go	Advanced usage of switch statements, including the use of fallthrough to execute subsequent case blocks.
2025-09-30	infiniteLoop.go	Basic structure of an infinite loop (which will be leveraged later for listeners/polling in system utilities).

3. Data Structures

Date	File	Concept & Documentation
2025-09-30	arrays.go	Defines and manipulates single- and multi-dimensional (2D) arrays, including iteration using for loops and element assignment/replacement. Demonstrates len() usage, index element swapping, and nested (2D) array access.
2025-10-10	slices.go	Advanced slice handling: creation, slicing, subslicing, append, capacity growth, element removal, copying, and iteration using both indexed and range-based loops. Includes troubleshooting notes on correct subslice indexing.
2025-10-10	maps.go	Complete map CRUD operations and iteration: create, read, update, delete, truncation, and existence checks using comma–ok idiom. Highlights mutability, zero-value behavior, and reference type behavior of maps.

4. Structs and Methods

Date	File	Concept & Documentation
2025-12-08	smithStruct.go	Struct definition, instantiation methods (field-by-field and inline literal), struct comparison with ==/!=, slice of structs, iteration with range, Go-syntax formatting with %#v.
2025-12-08	methods.go	Methods attached to structs, pointer receivers vs value receivers, modifying struct fields through methods.

5. CLI Tooling

Date	File	Concept & Documentation
2025-12-07	tipTaxCalculator.go	Closures and higher-order functions: Demonstrates functions that return functions, closures that capture state, multiple return values, and struct field access from slices. Includes troubleshooting notes on function signature matching, parentheses around multiple return types, and capturing all return values. Real-world application: CLI tool for calculating sales tax and tips across multiple locations.
