JavaScript Expressions as Props.
You can put any JavaScript expressions within braces inside JSX.
JavaScript expressions(but not statements) can be used inside JSX with curly brackets{}.
Normally, JavaScript expressions inserted in JSX will evaluate to a string, a React element, or a list of those things. However, props.
You can put any valid JavaScript expression inside the curly braces in JSX. For example, 2 + 2, user.
After compilation, JSX expressions become regular JavaScript function calls and evaluate to JavaScript objects.
How do you access the matched groups in a JavaScript regular expression?
It works because in JavaScript, true && expression always evaluates to expression, and false && expression always evaluates to false.
If statements and for loops are not expressions in JavaScript, so they can't be used in JSX directly. Instead, you can put these in the surrounding code. For example.
In this context"the text" is just a string variable, but the operations available are the same.Some programming languages(Perl, JavaScript) even provide dedicated syntax for regular expression operations.
