Example 3

medium
Given array `names = ['Alice', 'Bob', 'Charlie']`, what is names[1]? What happens if you access names[3]?

Solution

  1. 1
    Step 1: names[1] = 'Bob'.
  2. 2
    Step 2: names[3] would be an index out of bounds error — the valid indices are 0, 1, 2.

Answer

names[1] = 'Bob'. names[3] causes an index out of bounds error.
Accessing an index beyond the array length is a common bug. Always ensure the index is between 0 and length − 1.
