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.
const name = "Josh Perez";
const heading = <h1>Hello, {name}!</h1>;
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:
const x = 7;
const y = 10;
const sentence = <p>The sum of {x} and {y} is {x + y}</p>
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:
const score = 90;
const remarks = <p>You have {score > 50 ? "passed" : "failed"} the test.</p>
The output for the above expression will be:
You have passed the test.
