Suppose I have an array called arr1 and an object named arr2 containing a nested array called config.
If the key in the object from arr1 matches with an id within the nested config and further within the questions array, then replace that key (in the arr1 object) with the value of the title property found next to that id.
Let's see an example. The key isWorking from arr1 is the same as the id value in arr2.config[0].questions[0], so change the isWorking key to the value found in
arr2.config[0].questions[0].custom.titlevar arr1= [
{"jobs": "Marketing","isWorking": yes,"country": "MY"},
{"country": "IN","members": 4}
]
var arr2=
{
"id":1,
"name":"xxx",
"config":[
{
"questions":[
{
"id":"isWorking",
"custom":{
"title":"Are you working?"
}
},
{
"id":"jobs",
"custom":{
"title":"Please specify job(s)"
}
}
]
},
{
"questions":[
{
"id":"country",
"custom":{
"title":"which Country?"
}
},
{
"id":"members",
"type":"choices",
"custom":{
"title":"How many members?"
}
}
]
}
]
}
Expected output:
[
{"Please specify job(s)": "Marketing","Are you working": yes,"which Country": "MY"},
{"which Country": "IN","How many members": 4}
]
I attempted:
var result = arr1.map(e => ({
arr2.config.find(i => {
i.questions.find( q => {
q.id === Object.key(e) ? Object.key(e) === q.custom.title : q.id
}
})
}))
