7. Niklas Kiefer - Hour of Code Tech Talk - 12.11.2019 What is a Code Snippet? Everything one team member see a problem or had difficulties to understand or follows bad patterns if (action === 'create-bpmn-diagram') { return this.createDiagram('bpmn'); } if (action === 'create-dmn-diagram') { return this.createDiagram('dmn'); } if (action === 'create-dmn-table') { return this.createDiagram('dmn', { table: true }); } if (action === 'create-cmmn-diagram') { return this.createDiagram('cmmn'); } renderer.on('external:open-url', function(options) { const url = options.url; // .. }); renderer.on('dialog:open-files', async function(options, done) { const { activeFile } = options; // .. }); renderer.on('dialog:save-file', async function(options, done) { const { file } = options; // .. }); 7
