/**

|
* Creates a new object composed of the properties that do not satisfy the predicate function.
|
|
*
|
|
* This function takes an object and a predicate function, and returns a new object that
|
|
* includes only the properties for which the predicate function returns false.
|
|
*
|
|
* @template T - The type of object.
|
|
* @param {T} obj - The object to omit properties from.
|
|
* @param {(value: T[keyof T], key: keyof T, obj: T) => boolean} shouldOmit - A predicate function that determines
|
|
* whether a property should be omitted. It takes the property's value, key, and the source object as arguments and returns `true`
|
|
* if the property should be omitted, and `false` otherwise.
|
|
* @returns {Partial<T>} Returns the new object.
|
|
*
|
|
* @example
|
|
* const obj = { a: 1, b: 'omit', c: 3 };
|
|
* const shouldOmit = (value) => typeof value === 'string';
|
|
* const result = omitBy(obj, shouldOmit);
|
|
* // result will be { a: 1, c: 3 }
