hangulIncludes

Check if one hangul string includes another hangul string.

For example, 토스 includes 톳, and 값이 비싸다 includes 갑 or 빘.

function hangulIncludes(
  // The string to check if it includes the second argument `y`.
  x: string,
  // The string to check if it is included in the first argument `x`.
  y: string
): boolean;

Examples

hangulIncludes('토스', ''); // true
hangulIncludes('토스', 'ㅌ'); // true
hangulIncludes('토스', '톳'); // true
hangulIncludes('토스', '톱'); // false
hangulIncludes('토스', '토스'); // true
