Tests:

  • Ternary with Concat

     
    cacheName = (componentsCfg.v && componentsCfg.h) ? 'ch-' + componentsCfg.v + '-' + componentsCfg.h : 'ch';

  • Traditional If/Else with Concat

     
    if(componentsCfg.v && componentsCfg.h) {
        cacheName = 'ch-' + componentsCfg.v + '-' + componentsCfg.h;
    } else {
        cacheName = 'ch';
