Catch the Typos
This program should print Wings of Fire by A. P. J. Abdul Kalam, but it prints undefined by undefined. TypeScript already knows why: read the Types panel.
Fix the property names so it type-checks and prints the right sentence.
What Check tests
- Your code has no type errors
- The console prints
Wings of Fire by A. P. J. Abdul Kalam
