JSX Embedding Expressions

One of the main advantages of JSX is its capability to incorporate expressions directly into the code, enabling the inclusion of dynamic values within components or elements.

To include an expression in JSX, we enclose it within curly braces {}. This notation indicates to JSX that the contents should be treated as JavaScript.

The displayed value for the variable heading will be: Hello, Josh Perez! Similarly, you can do something more complicated and display the evaluated sum of two variables:

The output for the above expression will be: The sum of 7 and 10 is 17 It is also possible to embed ternary operators which can show conditional output:

The output for the above expression will be: You have passed the test.
