Pick Object Fields By Condition

pickObjectFieldsByCondition

The pickObjectFieldsByCondition function filters an object's properties by evaluating a predicate function (condition) against each key-value pair.

Function Signature

function pickObjectFieldsByCondition<T extends GenericObject>(
  source: T,
  condition: (key: keyof T, value: T[keyof T]) => boolean
): Partial<T>

Parameters

• source (T): The source object to filter.
• condition ((key: keyof T, value: T[keyof T]) => boolean): A function evaluated for each property. Return true to keep the property, or false to omit it.

Return Value

• Partial<T>: A new object containing only the properties that satisfy the condition.

Example Usage
