Omit

Removes specified fields from each object in an array, returning new objects.

Signature

Omit(array arr, array fields)

Parameters

arr (array): An array of objects.
fields (array): An array of field name strings to exclude.

Returns

array: A new array of objects containing all fields except those specified.

Description

Creates a new object for each source object containing all fields except those listed in fields. Non-object elements are skipped entirely (not included in the result). This is the inverse of Project, which keeps only specified fields.

Examples

var users = [
    { "name": "Alice", "age": 30, "ssn": "12345" },
    { "name": "Bob", "age": 25, "ssn": "67890" }
]

var clean = Omit(users, ["ssn"])
# clean = [
#   { "name": "Alice", "age": 30 },
#   { "name": "Bob", "age": 25 }
# ]

# Remove multiple fields
var minimal = Omit(users, ["age", "ssn"])
# minimal = [
#   { "name": "Alice" },
#   { "name": "Bob" }
# ]
