1-count.js

let count = 0;

count = count + 1;

// Line 1 is a variable declaration, creating the count variable with an initial value of 0
// Describe what line 3 is doing, in particular focus on what = is doing
// Line 3 is incrementing the value of count. The = operator is an assignment operator, which assigns the result of the expression on the right (count + 1) to the variable on the left (count). So, after line 3 is executed, count will have a new value that is one greater than its previous value.
