Recap

In the first lesson, we learned that:

• We can print to the console using the console.log() function.
• We write text in quotes "", numbers not.
• We have the following arithmetic operations: + (addition), - (subtraction), * (multiplication), / (division), % (integer remainder).
• Single-line comments are created by inserting // in the line, and everything in the line after this character is ignored by the computer.
• Multi-line comments are created by inserting /* at the beginning and */ at the end.
• We store information in variables to be used later in the program.
• We can create, overwrite, and use a variable with let.
• We can only create and use a variable with const.
• We can concatenate text using the + sign.

Congratulations on completing the first JavaScript lesson! In the next lesson, we will learn how to use conditionals for variable program behavior!
