I've an object like this:
const obj = {a: {x: 0, y: 0}}
that could be also:
const obj = {a: {x: 0, y: 0}, b: {x: 10, y: 3}, abcd: {x: -1, y: 0}}
So, the obj can have more than one key and with variables key names.
I need to replace each x value with a a string like this ${x}% so the x value + the percentage symbol.
How can I do that?
The expected results should be:
const obj = {a: {x: 0, y: 0}} // {a: {x: '0%', y: 0}}
const obj = {a: {x: 0, y: 0}, b: {x: 10, y: 3}, abcd: {x: -1, y: 0}} // {a: {x: '0%', y: 0}, b: {x: '10%', y: 3}, abcd: {x: '-1%', y: 0}}
I tried looping the object but I don't know if there is a smartest solution
const obj = {a: {x: 0, y: 0}, b: {x: 10, y: 3}, abcd: {x: -1, y: 0}}
let result = Object.fromEntries(Object.entries(obj).map(([k,v]) => {
return [k,{...v,x:`${v.x}%`}]
}))
console.log(result)
You can also check the object recursively. So no matter how deep the object goes every given key that matches gets a suffix.
I also make sure to create a copy of the object to prevent altering the original object(s).
const obj = {a: {x: 0, y: 0}, b: {x: 10, y: 3}, abcd: {x: -1, y: 0}};
const addSuffixToObj = (obj, key, suffix) => {
const copy = {...obj};
Object.keys(copy).forEach((prop) => {
if (typeof copy[prop] === 'object') {
copy[prop] = addSuffixToObj(copy[prop], key, suffix);
}else if(prop === key){
copy[prop] = copy[prop] + suffix;
}
});
return copy;
}
// Add "%" to all "x" keys
const result = addSuffixToObj(obj, 'x', '%');
console.log(result);
