I have the following array:
[
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
]
I need this:
[
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap)"],
["Cast", "Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
]
Here's my code:
const source = [
["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Basic)"],
["Cast", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap)"]
];
source.flatMap(([key, value1, value2, value3, value4, value5, value6, value7, value8, value9, value10, value11, value12, value13, value14, value15, value16]) => {
const values = value16.split(', ')
var hjk = values.map(singleValue => [key, singleValue])
console.log(hjk);
})Here's a jsfiddle of it working.
Is there a better way to do this? Putting value1, value2 etc seems silly.
You could destructure the wanted values and map the wanted pairs.
const
source = [["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Basic)"], ["Cast", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"], ["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap)"]],
result = source.flatMap(({ 0: key, 16: values }) => values
.split(', ')
.map(value => [key, value])
);
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }You could do this:
const source = [
["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Basic)"],
["Cast", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "Vehicle Graphics (Part Wrap)"]
];
source.flatMap((arr) => {
let [key] = arr;
let value16 = arr[16];
const values = value16.split(', ')
var hjk = values.map(singleValue => [key, singleValue])
console.log(hjk);
})
