The problem
I have a dataset encompassing empty columns. This dataset is obtained by getValues() of a defined range. Since I'll be storing this data set, I'd like to remove empty columns prior to that and, therefore, these columns need to be removed.
Dataset Sample
[
["120/1","2022-02-01T03:00:00.000Z","2022-02-01T03:00:00.000Z","Cartão Crédito","","Sicredi","","Visa","","1 + 6x","","1 de 7",100],
["120/2","2022-02-01T03:00:00.000Z","2022-03-01T03:00:00.000Z","Cartão Crédito","","Sicredi","","Visa","","1 + 6x","","2 de 7",100]
]
The evil code snippet (to me)
const colsVazias = [11, 9, 7, 5];//"Columns/elements" to be removed
for (let i = colsVazias.length - 1; i >= 0; i--) {
for (let r = 0; r < pagtos.length; r++) {
pagtos[r].splice(colsVazias[i], 1)
}
}
I have also tried this one (borrowed from @nnnnnn), but I can't tweak it to meet the demand here. Most likely, because we're dealing with different dimensions here...
var valuesArr = ["v1","v2","v3","v4","v5"],
removeValFromIndex = [0,2,4];
for (var i = removeValFromIndex.length -1; i >= 0; i--)
valuesArr.splice(removeValFromIndex[i],1);
Expected output:
[
["120/1","2022-02-01T03:00:00.000Z","2022-02-01T03:00:00.000Z","Cartão Crédito","Sicredi","Visa","1 + 6x","1 de 7",100],
["120/2","2022-02-01T03:00:00.000Z","2022-03-01T03:00:00.000Z","Cartão Crédito","Sicredi","Visa","1 + 6x","2 de 7",100]
]
Appreciate any help!
A simple map/filter combo would do it
let pagatos = [
["120/1","2022-02-01T03:00:00.000Z","2022-02-01T03:00:00.000Z","Cartão Crédito","","Sicredi","","Visa","","1 + 6x","","1 de 7",100],
["120/2","2022-02-01T03:00:00.000Z","2022-03-01T03:00:00.000Z","Cartão Crédito","","Sicredi","","Visa","","1 + 6x","","2 de 7",100]
];
let remove = [10, 8, 6, 4]
pagatos = pagatos.map(p => p.filter((v,i) => !remove.includes(i)))
console.log(pagatos)
