Description

Introduction

This course focuses on applying Test-Driven Development (TDD) using Jasmine to build high-quality JavaScript applications. Participants will learn how to write tests first, implement clean and efficient code, and continuously refactor with confidence. The training emphasizes practical TDD workflows, helping developers create robust, maintainable, and well-tested JavaScript codebases.

Prerequisites

Basic knowledge of JavaScript
Understanding of functions, objects, and modules
Familiarity with development tools like npm and code editors
Basic awareness of software testing concepts is helpful but not required
