React JSX If Statements

This lesson is part of React · All levels

Summary

JSX does not support the syntax if in curly braces, so the logic of the branching should be written in a different way. Common options are ternary operators, && operators to display certain conditions, or store the results of the conditions into variables before they are used in JSX. This approach keeps the JSX easy to read.

Key points

If it can't be written directly in {}
The ternary operator is suitable for the choice of two branches
The && operator displays elements only when the condition is worth true
Save the JSX conditional to a variable or a separate function when the logic is long
