/**
* Assigns properties from multiple source objects to a target object.
*
* This function merges the properties of the source objects into the target object.
* If a property in the source objects is equal to the corresponding property in the target object,
* it will not be overwritten.
*
* @param object - The target object to which properties will be assigned.
* @param sources - The source objects whose properties will be assigned to the target object.
* @returns The updated target object with properties from the source objects assigned.
*
* @example
* const target = { a: 1 };
* const result = assign(target, { b: 2 }, { c: 3 });
* console.log(result); // Output: { a: 1, b: 2, c: 3 }
