JavaScript Algorithm Basics: Building Functions from Scratch

When starting out with programming, relying too heavily on built-in language helpers can prevent you from truly understanding how software works under the hood. To write great code, you need to master the logical building blocks that power every application. This text-based course guides you through the process of thinking like a programmer, teaching you how to design, write, and test your own custom JavaScript functions from the ground up. By completing this course, you will transition from simply writing code to understanding the precise flow of execution, logical comparisons, and error handling. What you'll learn: - Understand the foundational concepts of JavaScript functions, parameters, and return values. - Master conditional logic using standard if-else statements and modern ternary operators. - Apply comparison operators to evaluate numerical relationships without built-in library methods. - Practice writing clean, readable, and modern JavaScript using ES6 syntax. - Test your custom functions against edge cases, including equal values and unexpected data types. - Develop algorithmic thinking patterns that apply to complex coding challenges in any language. The course begins with key terminology, basic concepts, and foundational definitions of functions and logic. From there, you will move directly into guided written exercises and code-based challenges designed to build your confidence and logical reasoning. This course is designed for absolute beginners who want to move beyond basic syntax and start solving actual programming problems. No prior coding experience is required.
