@lookwe/omit-undefined/omit-undefined.js

A small utility package for TypeScript and JavaScript projects to create a new object with all `undefined` properties removed, with strong support for TypeScript's `exactOptionalPropertyTypes`.

/**
 * Creates a new object containing only the properties of the input object that are not `undefined`.
 *
 * @param {T} obj  - The object to process.
 * @returns {OmitUndefined<T>} A new object with properties that were not `undefined` in the original object.
 * @template T  - An object type.
 */

    const cleanedObj = { ...obj };
    for (const key in cleanedObj) {
        if (cleanedObj[key] === undefined) {
            delete cleanedObj[key];
        }
    }
    return cleanedObj;
}
