How @bem/sdk.naming.file.stringify works?

const bemNaming = require('@bem/sdk.naming.entity'); // This is required, cause RunKit cannot load this package itself. const originNaming = require('@bem/sdk.naming.presets/origin'); const stringify = require('@bem/sdk.naming.file.stringify')(originNaming); const BemFile = require('@bem/sdk.file'); // Create a BEM file object to test the stringify() function. const file = BemFile.create({ block: 'b1', elem: 'e1', mod: {name: 'm1', val: 'v1'}, tech: 'js', layer: 'desktop', level: 'node_modules/bem-core' }); stringify(file);
