How do i get the value of an object in a object string-CodePudding

Hello there im kinda new to this so what i want to do is

    "string2": {
        "value": ""
    }
}

var path = ["string2","value"]

can i somehow get the value with the path i tried alot of things but nothing really worked

CodePudding user response：

You can use Array.reduce() for this:

const value = path.reduce((accum, key) => accum[key], string)

You can use a loop to traverse the path step by step as follows:

const str = { "string2": { "value": "Message" } };

const path = [ "string2", "value" ];

let output = str;
path.forEach(key => {
    output = output[key];
});

console.log( output );
