## Iteration: `{#for}`

Rust

```
let fields = vec!["name", "email", "age"];

let code = ts_template! {
    function toJSON() {
        const result = {};
        {#for field in fields}
            result.@{field} = this.@{field};
        {/for}
        return result;
    }
};
```

**Generates:**

TypeScript

```
function toJSON() {
  const result = {};
  result.name = this.name;
  result.email = this.email;
  result.age = this.age;
  return result;
}
```

### Tuple Destructuring in Loops

Rust

```
let items = vec![("user", "User"), ("post", "Post")];

let code = ts_template! {
    {#for (key, class_name) in items}
        const @{key} = new @{class_name}();
    {/for}
};
```

### Nested Iterations

Rust

```
let classes = vec![
    ("User", vec!["name", "email"]),
    ("Post", vec!["title", "content"]),
];

ts_template! {
    {#for (class_name, fields) in classes}
        @{class_name}.prototype.toJSON = function() {
            return {
                {#for field in fields}
                    @{field}: this.@{field},
                {/for}
            };
        };
    {/for}
}
```
