I have 2 arrays with different lengths
let daysArray = ['09-20', '09-21', '09-22', '09-23', '09-24', '09-25', '09-26']
let weekNameArray = ['Mi', 'Do', 'Fr', 'Sa + So', 'Mo', 'Di' ]
combined them with _.zipWith:
let weakDateArr = _.zipWith(weekNameArray, daysArray , function(first, second) {
return first + " " + second
});
How I can combine them to get the next array:
['Mi 09-20', 'Do 09-21', 'Fr 09-22', 'Sa + So', 'Mo 09-25', 'Di 09-26']
'Sa + So' must be undated *
Hmm, not sure lodash has support for this out of box...
You could apply a simple custom solution using Array.map() and an index offset for the daysArray:
days_offset = 0;
let combined = weekNameArray.map( (name, index) => {
if(name.length <= 2) {
return name + ' ' + daysArray[ index - days_offset ];
} else {
days_offset += 1;
return name;
}
});
