Who Should Attend?

This is considered a foundational course. Best for individuals who are new to programming and starting their full-stack career.

What You'll Learn
  • Utilize tools used in programming such as VS Code and run JavaScript files locally.
  • Understand the basic concepts of programming and JavaScript's role in web development.
  • Create variables that store different data types and manipulate the values using operators in JavaScript.
  • Use JavaScript built-in libraries, like `console`, to work with primitive data types.
  • Implement control flow using `if`, `else if`, `else`, `switch`, and ternary syntax in JavaScript.
  • Create functions using all of JavaScript's different syntax that use parameters — and call them with arguments to return values.
  • Interpret common JavaScript errors and interpret error messages.
  • Purposefully define values and objects in a scope that is accessible to the objects that require said values and other objects in JavaScript.
  • Store, access, and manipulate elements in an array in JavaScript.
  • Use loops that have defined starting, stopping, and continuing conditions to iterate over elements in a collection in JavaScript.
