+/**
+ * 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 obj - The object to omit properties from.
+ * @param shouldOmit - A predicate function that determines
+ * whether a property should be omitted. It takes the property's key and value as arguments and returns `true`
+ * if the property should be omitted, and `false` otherwise.
+ * @returns A new object with the properties that do not satisfy the predicate function.
+ *
+ * @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 }
