include icon-components/functions/icon-exists/intro

Usage

include icon-components/functions/icon-exists/props

Example

function renderLeftArrow() {
	// Check if 'bi:arrow-left' is available
	if (Iconify.iconExists('bi:arrow-left')) {
		// Return HTML for 'bi:arrow-left'
		return Iconify.renderHTML('bi:arrow-left');
	}

	// Load icon. Bad example because this should use a callback to re-render arrow, but
	// this code example is about iconExists(), not loadIcons()
	Iconify.loadIcons(['bi:arrow-left']);

	// Return '<'
	return '&lt;';
}
