Example
Bad:
=IF(A2>100,"High",IF(A2>50,"Medium","Low"))
Better:
=IFS(
A2>100,"High",
A2>50,"Medium",
TRUE,"Low"
)
11. Array Formulas and Dynamic Arrays

=CALCULATE_TAX(amount)
15. Lookup Systems and Relational Thinking
Developers should treat Sheets
relationally.
Lookup Functions
VLOOKUP
=VLOOKUP(A2,D:F,2,FALSE)
INDEX + MATCH
More flexible:
