I have a specific type of object, and I am looking to extract the values from this object into a separate array. The keys in this new array will be based on the values of the original object's keys after the underscore.
Here is the current input:
{"1_1":[1,2],"2_1":[2,1,3],"3_2":[4,5],"4_2":[6,7]}
The expected output should look like this:
[
1: [1, 2, 3],
2: [4, 5, 6, 7]
]
Go through your dictionary and create a new one with keys that are the values of the original keys after an underscore (_) by using the split function. Then, check if the expected object already has an array with this key using hasOwnProperty. If not, append the value of the iterated element to the expected object.
Give this a shot:
input = {
"1_1": [1, 2],
"2_1": [2, 1, 3],
"3_2": [4, 5],
"4_2": [6, 7]
}
expected={}
for (e in input){
if (!expected.hasOwnProperty(e.split('_')[1])){
expected[e.split('_')[1]]=[]
}
input[e].forEach((r)=>{
if (!expected[this.e.split('_')[1]].includes(r)){
expected[this.e.split('_')[1]].push(r)
}
})
}
console.log(expected)The includes method is used to prevent duplicate values in the expected object's values.
