You can filter a list in lodash to get every other value. This is useful if, e.g. you are using solr, which returns facet results as a list of alternating facet name and the count (i.e. [“DropBox”, 100, “GoogleDocs”, 10, “OneDrive”, 0])<\/p>\n
If you want the odd values:<\/p>\n
\n_.filter(['a','b','c','d'], \n (value, idx) => idx % 2 === 0\n);\n\n['a', 'c']\n<\/pre>\nIf you want the even values:<\/p>\n
\n_.filter(['a','b','c','d'], \n (value, idx) => idx % 2 === 1\n);\n\n['a', 'c']\n<\/pre>\nAs an alternate option, you can turn the list into lists of pairs, like so (you can turn this into a map with “fromPairs”).<\/p>\n
