Session 3

Conditions

• introduce basic syntax and structure of switch statement
• reassign variable value in different cases
• set default case
• discuss how switch statements differ from if...else statements

Array Iteration

• introduce basic syntax and structure of for...of loop
• discuss how for loops differ from for...of loops
• use for...of loops to iterate through an array and access each object within it
• for each object in an array, use dot notation to access the values of specific properties

Objects

• iterate through collections of objects using for...of loop
• iterate over an array of objects, generating string representations of each one by interpolating its property values into a string
• append each string to the existing value of a variable using the addition assignment operator: +=
• use dot notation to add a new property to each object in an array, and the assignment operator to assign value to it.

Functions

• review arrow function syntax
• discuss the difference between invoking a function and defining it
• capture the return value in a variable
