#some helper

Checks whether any element in an array satisfies a given condition function. If true for at least one, the main block is rendered; otherwise, the {{else}} block is rendered.

Usage

{{#some array conditionFn}} expressionInitial {{else}} expressionElse {{/some}}

  • array (required): array to evaluate

  • conditionFn (required): functionto apply to each element. Valid conditionFn include:

    • isFalsy

    • isTruthy

    • isArray

    • isString

    • isObject

    • isNumber

    • isBoolean

Examples

  1. Check if any array element is truthy

    {{#some record.arr isTruthy}}
  Truthy
{{else}}
  N/A
{{/some}}

    Input:

    { "record": { "arr": [1, "hello", true] } }

    Output:

    Truthy

  2. Check if any array element is a number

    {{#some record.values isNumber}}
  Contains a number
{{else}}
  No numbers
{{/some}}

    Input:

    { "record": { "values": ["apple", false, 42] } }

    Output:

    Contains a number

Tip

  • Use #some when you only need to know if at least one match exists, not all elements.

  • For arrays of objects where property matching is needed, use #filter.

  • The exhaustive supported list for ConditionFn is isFalsy, isTruthy, isArray, isString, isObject, isNumber, isBoolean.

  • Use #some to check existence of at least one match; if none match but parameters are valid, the {{else}} block renders.
