const a = {"b":{"c":3}}
const z = "b.c"
I have the above values and now I want to get value 3(a.b.c) from a using the z variable. I have tried the below method but it is not working
${a.z}${a[z]}You can do something like this
function rGetAttr(obj, dotPath){
return dotPath.split('.').reduce((o,i)=> o[i], obj)
}
const obj = {a: {b: {c: 123}}}
console.log(rGetAttr(obj, "a.b.c"))You can do it by using Lodash
const _ = require("lodash");
console.log(_.get(a, z));
You could do something like this:
const a = {
"b": {
"c": 3
}
}
const keyName = "b";
// This works to access an objects elements by key name
console.log(a[keyName]);
// If you want to be able to have "b.c" then you need to handle the nesting something like this:
const getValue = (obj, prop) => {
const parts = prop.split('.');
let thisObj = obj;
let part = 0;
while (thisObj = thisObj?.[parts[part++]]) {
if (part >= parts.length) break;
}
return thisObj;
}
const nestedKeyName = "b.c";
// Usage like this:
console.log(getValue(a, nestedKeyName));
