I have data like so:
{
"title": 0,
"name": 0,
"score": 0,
"summary": [
{
"id": 1,
"start": "2019-11-01",
"end": "2019-11-04"
},
{
"id": 2,
"start": "2019-11-01",
"end": "2019-11-04"
}
]
}
I am trying to access the first element of summary, so I have tried this:
const newDate = new Date(data?.summary.map((d: any, index: number) => {
if (index === 0) {
return (
new Date(d.start)
)
}
})),
although it's working i get the warning:
Array.prototype.map() expects a value to be returned at the end of arrow function array-callback-return
I know it must be because I am not returning anything in the callback and the return is in the if statement?
if (index === 0) {
return (
new Date(d.start)
)
You are only returning a value if index === 0.
Im not sure what are you trying to achieve:
const newDate = new Date(data?.summary.map((d: any, index: number) => {
if (index === 0) {
return (
new Date(d.start)
)
}
})),
I suppose:
const newDate = newDate(data?.summary[0]?.start)
Will do the thing.
You can access to the first element without using map function:
const newDate = new Date(data?.summary[0].start)
