JavaScript Essentials 1

• Proficiency in Core JavaScript Concepts: Develop a solid understanding of JavaScript syntax, semantics, and best practices, enabling you to design, write, debug, and run JavaScript programs.
• Foundational Programming Skills: Gain the ability to work with variables, data types, operators, control flow, and functions, forming a strong foundation in programming.
• Problem-Solving and Debugging: Learn to identify and fix syntactic, semantic, and logical errors, use debugging tools, and handle exceptions effectively.
• Preparation for Certification: Equip yourself with the skills needed to pursue JSE – Certified Entry-Level JavaScript Programmer and JSA – Certified Associate JavaScript Programmer certification exams.
• Portfolio Development: Start building a programming portfolio by creating and improving simple JavaScript programs, showcasing your skills to potential employers.

This course, designed by the OpenEDG JS Institute and implemented by Cisco Networking Academy, is the first part of a two-course series aimed at preparing you for certification as a JavaScript programmer. It provides a comprehensive introduction to programming with JavaScript, focusing on core language concepts, tools, and best practices. Through six detailed modules, you will progress from a complete beginner to a competent JavaScript developer capable of designing and debugging your own programs. The course not only prepares you for certification exams but also equips you with skills applicable to careers in web development, front-end development, and application testing.

• Beginners with no prior programming experience looking to learn JavaScript.
• Individuals interested in pursuing JavaScript programming certifications.
• Aspiring web developers seeking to gain a strong foundation in JavaScript.

• No prior programming knowledge is required.
• Basic computer skills and familiarity with using a web browser
