I wrote this code, still it return undefined
function Nbr1(a){
return a.toString().split('').map(Number).forEach( (item, index) => item + 1);

You don't need to use a forEach after map. map already iterates through the array.
And don't forget to convert the array item to a number with a + before it because you generated an array of strings
function Nbr1(a) {
return a.toString().split("").map((number) => +number + 1)
}
console.log(Nbr1(12345))

See short example below with usage of parseInt(). No extra forEach required.
function Nbr1(a){
return a.toString().split('').map((number)=>{
return parseInt(number) + 1
})
}
console.log(Nbr1(12345))
