I have recursive function which prints every child in a deeply nested object.
const tree = {
name: "Anand",
children: [
{
name: "Dashrath",
children: [
{
name: "Sitesh",
children: [
{
name: "Yadnesh",
children: []
}
]
}
]
},
{
name: "Machindra",
children: [
{
name: "Tejas",
children: [
{
name: "Tanishka",
children: []
}
],
},
{
name: "Amol",
children: [],
},
{
name: "Amit",
children: []
}
]
}
]
}
function printTree(t) {
if (t.children.length === 0) {
return
}
t.children.forEach((child,index) => {
console.log(child.name);
printTree(child);
})
}
printTree(tree);and I want something like this 1st gen dashrath, 2nd gen sitesh, 3rd gen yadnesh, 1st gen machindra, 2nd gen tejas, 3rd gen tanishka, 2nd gen amol, 3rd gen amit
You could have the printTree function accept a depth parameter and increment it appropriately with each recursive call, something like this:
function printTree(t, depth = 0) {
if (t.children.length === 0) {
return
}
t.children.forEach((child,index) => {
// you'd need to do some extra formatting here if you
// want ordinals like "1st", "2nd", etc.
console.log(`gen ${depth + 1}: ${child.name}`);
printTree(child, depth + 1);
})
}
printTree(tree);
