how can I get the values of a nested object in a loop? I need to iterate through both levels:
for (let unit in ds1.units) {
for (let ports in ds1.units[unit].switchPorts) {
console.log(ports)
}
}
}
Object looks like this:

There is no output. When I access the value with ds1.units[unit].switchPorts I get it. Also I get the unit after the first for loop.
You can't iterate Object by default.
Hence, there are multiple ways, but I prefer to convert the key to array.
So the code would be:
for (let unit of Object.keys(ds1.units)) {
console.log(ds1.units[unit].switchPorts)
}
Also we're going to use of instead of in because of going to retrieve the value instead of index.
For test case:
ds1 = {
units: {
1: {
switchPorts: 5,
},
2: {
switchPorts: 6,
}
}
}
for (let unit of Object.keys(ds1.units)) {
console.log(ds1.units[unit].switchPorts)
}
