## Control Flow

Liquid provides multiple control flow statements.

### if

    {% if customer.name == 'kevin' %}
      Hey Kevin!
    {% elsif customer.name == 'anonymous' %}
      Hey Anonymous!
    {% else %}
      Hi Stranger!
    {% endif %}

### unless

The opposite of `if` – executes a block of code only if a certain condition is not met.

    {% unless product.title == 'Awesome Shoes' %}
    These shoes are not awesome.
    {% endunless %}

### case

Creates a switch statement to compare a variable with different values. `case` initializes the switch statement, and `when` compares its values.

    {% assign handle = 'cake' %}
    {% case handle %}
      {% when 'cake' %}
        This is a cake
      {% when 'cookie' %}
        This is a cookie
      {% else %}
        This is not a cake nor a cookie
    {% endcase %}

### for

Repeatedly executes a block of code. break = Causes the loop to stop iterating when it encounters the break tag. continue = Causes the loop to skip the current iteration when it encounters the continue tag.

    {% for i in (1..10) %}
      {% if i == 4 %}
        {% break %}
      {% elsif i == 6 %}
        {% continue %}
      {% else %}
        {{ i }}
      {% endif %}
    {% endfor %}

### range

    {% for i in (3..5) %}
      {{ i }}
    {% endfor %}

    {% assign num = 4 %}
    {% for i in (1..num) %}
      {{ i }}
    {% endfor %}
