const obj2arr = (data, level) => {

}
};
res = obj2arr(b, 1);
console.log(res);You should not have those level++ and level-- instructions. Instead pass level - 1 to the recursive call:
obj["values"] = obj2arr(data[dataKey], level - 1);
This way the condition you already have (level > 0) will make sure that only up to the given level the transformation is made.
I didn't touch anything else in your code:
const obj2arr = (data, level) => {
const dataKeys = "object" === typeof(data) && !Array.isArray(data) && Object.keys(data);
let results = [];
if (!!dataKeys) {
for (let dataKey of dataKeys) {
let obj = {
name: dataKey
}
obj["values"] = data[dataKey] || null;
if ("object" === typeof(data[dataKey]) && !Array.isArray(data[dataKey]) &&
data[dataKey] && "object" === typeof(data[dataKey]) && level > 0) {
obj["values"] = obj2arr(data[dataKey], level - 1);
}
results = [...results, obj];
}
}
return results
}
let b = {
a: [1, 2],
b: 3,
c: 'c',
d: {
d1: 'bla',
d2: 'ble',
d3: {
e: 1,
f: [1, 2],
g: 'bli',
h: {
h1: 1,
h2: 2
}
}
}
};
res = obj2arr(b, 1);
console.log(res);
