When working with JSON data from an API, I often need to parse and modify specific property values. The challenge arises when the nesting structure of the JSON data is inconsistent and beyond my control.
For example, I cannot always rely on a fixed depth like parsedJson.children[0].property to find the desired property. It might be located at a different level, such as parsedJson.children[0].children[0].property in another instance.
Currently, I handle this by dynamically traversing the JSON object and modifying the desired property:
var parsedJson = JSON.parse('{"a":[{"a1":[{"p":0},{"np":1}]}],"b":[{"p":0},{"np":1}],"c":[{"c1":[{"c2":[{"p":0}]},{"np":1}]}]}')
console.log("before modify")
console.log(parsedJson)
modifyProperty(parsedJson,"p",1);
function modifyProperty(obj,prop,val){
for (var key in obj){
if (key == prop){
obj[key] = val;
}
modifyProperty(obj[key],prop,val);
}
}
console.log("after modify")
console.log(parsedJson)
However, I am concerned about potential performance issues when dealing with larger datasets and deeper nesting levels in future API responses. Repeatedly iterating through all child nodes could become inefficient.
Is there a more efficient or faster approach to accomplish this task?
