# Working with arrays and objects

# Arrays

An array is a collection of similar data elements.

# HTML

You can submit an array by using the name[index] syntax:

<form action="https://submit-form.com/your-form-id">
  <input type="text" name="ingredients[0]" placeholder="Ingredient 1" />
  <input type="text" name="ingredients[1]" placeholder="Ingredient 2" />
  <input type="text" name="ingredients[2]" placeholder="Ingredient 3" />
  <input type="text" name="ingredients[3]" placeholder="Ingredient 4" />
  <button type="submit">Send</button>
</form>

# AJAX

axios.post("https://submit-form.com/your-form-id", {
  ingredients: ["anchovies", "cheese", "flour", "tomato", "water"],
});

# Objects

An object is a standalone entity with properties.

# HTML

You can submit an object by using the name.property syntax:

<form action="https://submit-form.com/your-form-id">
  <input type="text" name="car.manufacturer" />
  <input type="text" name="car.color" />
  <button type="submit">Send</button>
</form>
