AllByField

Tests whether all objects in an array match a field condition.

Signature

AllByField(array arr, string fieldName, string operator, any value)

Parameters

arr (array): An array of objects to test.
fieldName (string): The property to compare. Supports dot notation.
operator (string): The comparison operator.
value (any): The value to compare against.

Returns

boolean: true if every element matches the condition.

Description

Iterates the array and evaluates the condition against each object’s field. Stops at the first non-match. Non-object elements cause the function to return false (they fail the “all” check).

Supported operators: ==, !=, <, <=, >, >=.

Null field handling: A null field passes != non-null and == null. All other comparisons against null fields fail.

For general-purpose predicate testing, see All which accepts a lambda.

Examples

var users = [
    { "name": "Alice", "active": true },
    { "name": "Bob", "active": true }
]

var allActive = AllByField(users, "active", "==", true)
# allActive = true

var allAdult = AllByField(users, "age", ">=", 18)
# allAdult = false (age field is null)
