Review

At this point we can:

  • Login to Replit, find our Team, and open available projects.

  • Print something to the developer console using console.log( )

  • Create variables with the let statement

    • let age;

  • Assign variables a value with =

    • age = 42;

  • Complete some basic math with +, -, *, /, **

Lesson

  • 𝜋 is not just 3.14.

  • What if the answer to some math problem has to be rounded to two decimals (like money)?

  • How can we turn a string into all UPPERCASE or lowercase letters?

  • What if we want to know the length of a string?
