AnyByField

Tests whether any object in an array matches a field condition.

Signature

AnyByField(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 at least one object matches the condition.

Description

Iterates the array and evaluates the condition against each object’s field. Stops at the first match. Non-object elements are skipped.

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

Null field handling: A null field matches != non-null and == null. All other comparisons against null fields are skipped.

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

Examples

var users = [
    { "name": "Alice", "age": 30 },
    { "name": "Bob", "age": 25 }
]

var hasAdult = AnyByField(users, "age", ">=", 30)
# hasAdult = true

var hasCarol = AnyByField(users, "name", "==", "Carol")
# hasCarol = false

# Dot notation
var orders = [
    { "customer": { "vip": true } },
    { "customer": { "vip": false } }
]
var hasVip = AnyByField(orders, "customer.vip", "==", true)
# hasVip = true
