I have an object set
var obj = {
ref01:{
test:"abc"
},
ref02:{
test:"xyz"
},
ref03:{
test:"pqr"
}
}
and I have new object
const test = {
test:"def"
}
I want to update the object above with increment value of ref Now ref is03 , I want to append like ref04 and increment each time based on existing obj.
var obj = {
ref01:{
test:"abc"
},
ref02:{
test:"xyz"
},
ref03:{
test:"pqr"
},
ref04:{
test:"def"
}
}
i tried object.assign but its directly passing the value .
obj = object.assign(obj,{ref:test})
So how can i get it ?
I think you want a list: i.e.
const obj = {
testObjects: [
{
test: 'abc'
},
...
]
}
then you can just run:
obj.testObjects.push({test: 'xyz'});
OR if this is an API response you can't change the schema of:
//find last index so you can add the ref obj
const getFormattedIndex = (idx) => String(idx).padStart(2, '0');
let i = 1;
while(obj[`ref${getFormattedIndex(i)}`]) {
i++;
}
//add object with the correct sequential key
obj[`ref${getFormattedIndex(i)}`] = {test: 'xyz'};
or you could be a bad person and use scope-bleed with a ghetto for loop 😇:
//find last index so you can add the ref obj
const getFormattedIndex = (idx) => String(idx).padStart(2, '0');
for (var i = 1; obj[`ref${getFormattedIndex(i)}`]; i++);
//add object with the correct sequential key
obj[`ref${getFormattedIndex(i)}`] = {test: 'xyz'};
