Hi I am transforming JSON
I have write the following program to add newName in the JSON array
If you take a look resultedEvents, categoryName and name is missing in the JSON.
const result2 = {
"resultedEvents": [
{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa",
"resultedMarkets": [
{
"name": "Asian Handicap",
},
]
},
{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa (Live)",
"resultedMarkets": [
{
"name": "Asian Handicap -0.5 (1-3)",
}
]
}
]
}
const data2= result2.resultedEvents.map(items => {
const newResult = items.resultedMarkets.map(function (item) {
const newName = item.name.replace(/( -?\d+([.,]\d+)?)/g, "");
return {...item, newName};
})
return { resultedMarkets: newResult }
}
);
console.log(data2)Above program is giving me following
Output
[
{
"resultedMarkets": [
{
"name": "Asian Handicap",
"newName": "Asian Handicap"
}
]
},
{
"resultedMarkets": [
{
"name": "Asian Handicap -0.5 (1-3)",
"newName": "Asian Handicap (1-3)"
}
]
}
]
Expected
{
"resultedEvents": [{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa",
"resultedMarkets": [{
"name": "Asian Handicap",
"newName": "Asian Handicap"
}
]
},
{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa (Live)",
"resultedMarkets": [{
"name": "Asian Handicap -0.5 (1-3)",
"newName": "Asian Handicap (1-3)"
}]
}
]
}
Please help me to solve this issue I just want to add newName in the JSON rest should be as it is
>Solution :
you are returning only resultedMarkets in your outer map
just add ...items like this
const result2 = {
"resultedEvents": [
{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa",
"resultedMarkets": [
{
"name": "Asian Handicap",
},
]
},
{
"categoryName": "Football",
"name": "Arsenal vs Aston Villa (Live)",
"resultedMarkets": [
{
"name": "Asian Handicap -0.5 (1-3)",
}
]
}
]
}
const data2= result2.resultedEvents.map(items => {
const newResult = items.resultedMarkets.map( item => {
const newName = item.name.replace(/( -?\d+([.,]\d+)?)/g, "");
return {...item, newName};
})
return {...items, resultedMarkets: newResult }
}
);
console.log(data2)
