Conditional Helpers

For a full list of comparators view the dedicated section on comparison helpers

Existence

You can use exists and isEmpty to handle value existence. Values are checked against the isEmpty utility.

{#if exists valueToCheck}
  Value exists
{/if}

{#if isEmpty collectionToCheck}
  Collection is empty
{/if}

Equality

You can use is not, isExactly and isNotExactly helpers to compare values

Exactly helpers use === comparison while is and not use ==

{#if is valueA valueB}
  Values are equal
{/if}

{#if not isEven number}
  Odd
{else}
  Even
{/if}

Comparisons

You can use greaterThan, lessThan, greaterThanEquals, lessThanEquals to compare numeric values

{#if greaterThan numberA numberB}
  A is greater than B
{/if}

{#if lessThanEquals numberA numberB}
  A is less than or equal to B
{/if}
