What are other uses for curly braces?

Curly braces {} have several uses across different programming languages. Here are some common applications:

Code Blocks: As mentioned, they define blocks of code for control structures (e.g., if, for, while).
Function Definitions: In languages like C, C++, and Java, curly braces enclose the body of functions.
```
void myFunction() {
    // Function body
}
```
Object Literals: In JavaScript, curly braces define object literals.
```
const person = {
    name: "Alice",
    age: 30
};
```
Set Notation: In mathematics and programming, curly braces can denote sets.
```
my_set = {1, 2, 3}
```
String Interpolation: In languages like Python (with f-strings) and Ruby, curly braces are used for embedding expressions within strings.
```
name = "Alice"
print(f"Hello, {name}!")
```
Template Literals: In languages like JavaScript, they can be used in template literals for multi-line strings and variable interpolation.
```
const greeting = `Hello, ${name}!`;
```
