How to use the change-case.ucFirst function in change-case

Object.keys(moduleMap).forEach(function(moduleType) {
		var filePaths = moduleMap[moduleType];
		if (filePaths.length < 1) {
			return;
		}

		contents += '	// ' + changeCase.ucFirst(moduleType) + 's\n';

		filePaths.forEach(function(file) {
			var moduleName = file.name;
			var modulePath = file.path.replace('\\', '/');

			contents += '	app.' + moduleType + '(';

			// precede animations with a `.`
			if (moduleType === 'animation') {
				moduleName = '.' + moduleName;
			}

			// config modules don't have a name
			if (moduleType !== 'config') {
				contents += '\'' + moduleName + '\', ';
			}
