Lesson 4.4: Multiple Conditional Statements

🔀 Multiple Conditions

• Understanding if and else statements.
• Analyze and explain the given code snippets.

Example: Basic Conditional

if(hideText === "on") {
  document.querySelector("p").display = "none";
} else {
  document.querySelector("p").display = "block";
}

• Discussion: What happens when the condition is true/false?

Grade Example: Before else if

if(grade >= 90) {
  alert("Grade: A");
} else {
  alert("Grade: F");
}

• Issue: This code does not cover grades between 89 and 0.

Grade Example: Using else if

if(grade >= 90) {
  alert("Grade: A");
} else if (grade >= 80) {
  alert("Grade: B");
} else if (grade >= 70) {
  alert("Grade: C");
} else {
  alert("Keep trying!");
}

Multiple If-Else Conditions

let day = "Friday";

if(day === "Monday") {
  alert("HW is due");
} else if (day === "Friday") {
  alert("Early dismissal");
} else if (day === "Saturday") {
  alert("Go to the movies");
} else {	
  alert("Relax!");
}
