I'm trying to write a function but I doesn't make it. This function works like that
Input: changeSetting("a>b>c","hello")
After that "setting" named value change from {} to {"a":{"b":{"c":"hello"}}}
If input is changeSetting("a","hello") json become {} to {"a":"hello"}
My last code attempt:
function changeSetting(name,val) {
if (name.includes(">")) {
name = name.split('>')
let json = {}
name.map((el,i)=>{
let last = ""
name.filter(el=>!name.slice(i+1).includes(el)).map(el=> {
if(last!="") {
json[el] = {}
}})
})
}
}
How can we make this ? (Optimization not important but if is it good for me)
const changeSetting = (setting, target) => {
if (setting.length < 2) {
return {
[setting]: target
}
} else {
const keys = setting.split('>');
return keys.reduceRight((acc, curr, i) => {
console.log(acc);
if(i === keys.length - 1) {
return acc = {[curr] : target}
}
return acc = { [curr]: acc };
}, {})
}
}
console.log(changeSetting('a', 'hello'));
console.log(changeSetting('a>b>c', 'hello'));
function changeSetting(inputProperties, value) {
let result;
const properties = inputProperties.split(">");
result = `{${properties
.map((property) => `"${property}":`)
.join("{")}"${value}"${"}".repeat(properties.length)}`;
return result;
}
changeSetting("a>b>c", "hello");
changeSetting("a", "hello");
There's multiple ways to do this, I've commented the snippet
const changeSetting = (name, val) => {
// Split and reverse the name letters
const nameSplit = name.split('>').reverse();
// Set up the inner most object
let newObj = {[nameSplit[0]]:val}
// Now remove the first letter and recurse through the rest
nameSplit.slice(1).forEach((el, idx) => newObj = {[el]: newObj});
console.log(newObj);
}
changeSetting("a>b>c", "hello")
changeSetting("a", "hello")
changeSetting("a>b>c>d>e>f>g", "hello")
