How to use the color-convert.hasOwnProperty function in color-convert

styles.bgColor.close = '\u001b[49m';

	styles.color.ansi = {};
	styles.color.ansi256 = {};
	styles.color.ansi16m = {
		rgb: wrapAnsi16m(rgb2rgb, 0)
	};

	styles.bgColor.ansi = {};
	styles.bgColor.ansi256 = {};
	styles.bgColor.ansi16m = {
		rgb: wrapAnsi16m(rgb2rgb, 10)
	};

	for (var key in colorConvert) {
		if (!colorConvert.hasOwnProperty(key) || typeof colorConvert[key] !== 'object') {
			continue;
		}

		var suite = colorConvert[key];

		if ('ansi16' in suite) {
			styles.color.ansi[key] = wrapAnsi16(suite.ansi16, 0);
			styles.bgColor.ansi[key] = wrapAnsi16(suite.ansi16, 10);
		}

		if ('ansi256' in suite) {
			styles.color.ansi256[key] = wrapAnsi256(suite.ansi256, 0);
			styles.bgColor.ansi256[key] = wrapAnsi256(suite.ansi256, 10);
		}

		if ('rgb' in suite) {
