Nested Conditionals Javascript Homework

Practice Problems:

Problem 1: Age and Movie Rating

Write a program that asks for a person’s age. If they are under 13, print “You can watch G or PG movies.”

• If they are 13–17, print “You can watch PG-13 movies.”
• If they are 18 or older, print “You can watch R-rated movies.”

%%js
let age = parseInt(prompt("Enter age:"));

// Nested conditionals
if (age < 13) {
  console.log("You can watch G or PG movies.");
} else {
  if (age < 18) {
    console.log("You can watch PG-13 movies.");
  } else {
    console.log("You can watch R-rated movies.");
  }
}

Problem 2: Grade Categorizer

Ask the user for a grade percentage (0–100).

• If the grade is 90 or higher, log “A”.
• Else if it is 80–89, log “B”.
• Else if it is 70–79, log “C”.
• Else if it is 60–69, log “D”.
• Otherwise, log “F”

%%js
let grade = parseInt(prompt("Enter grade percentage: "));

// Nested conditionals
if (grade >= 90) {
  console.log("A");
} else {
  if (grade >= 80) {
    console.log("B");
  } else {
    if (grade >= 70) {
      console.log("C");
    } else {
      if (grade >= 60) {
        console.log("D");
      } else {
        console.log("F");
      }
    }
  }
