How to use textextensions - 4 common examples

function isTextSync(filename, buffer) {
	// Test extensions
	if (filename) {
		// Extract filename
		const parts = pathUtil
			.basename(filename)
			.split('.')
			.reverse()

		// Cycle extensions
		for (const extension of parts) {
			if (textExtensions.indexOf(extension) !== -1) {
				return true
			}
			if (binaryExtensions.indexOf(extension) !== -1) {
				return false
			}
		}
	}

	// Fallback to encoding if extension check was not enough
	if (buffer) {
		return getEncodingSync(buffer) === 'utf8'
	}

	// No buffer was provided
	return null
}
