You can also pass options to minify. Here is list of default options:

`js
({
quotes: ',
fixCount: 1, // the more fixCount - less output size
conditions: false,
mangleClassNames: true,
mangle: true,
mergeVariables: true,
removeUnusedVariables: false,
removeConsole: false,
removeUselessSpread: true,
applyTemplateLiterals: true,
convertStrictEqualToEqual: false,
});
`

And usage example:

`js
import {minify} from '@putout/minify';

const source =
const a = 5;
const b = 6;
;

minify(source, {
removeUnusedVariables: false,
});
``
