Question

Manipulating properties within Javascript objects is a common task in web development. By

Just diving into the world of javascript and have a question to ask (obviously :P). I've developed two methods - one fetches value from an object based on its data path (structure within an object like "object.subObject.anotherSubObject.property"), and another sets a value to an object using the data path.

Check out the TypeScript code snippet below:

public getValueFromObject(object:any, path:string|string[], thisArg:any = null):any {
    // code for fetching value from object...
}

private setValueToObject(dataObject:any, value:any, dataPath:string|string[], thisArg:any = null):any {
    // code for setting value to object...
}

My query is about the quality of this JavaScript code. Are there any libraries, like lodash, that could simplify what I'm attempting to achieve? It would be great if someone could provide an example code. Thank you in advance!

Answer №1

Manipulating objects in JavaScript is quite flexible.

Create a new object

var myobj = {
    var1: 'hello'
}

Retrieve var1

console.log(myobj.var1) // 'hello'

Update var1

myobj.var1 = 'world'

Retrieve var1 once more

console.log(myobj.var1) // 'world'

Combine everything to display 'hello world' on your console

var myobj = { var1: 'hello' };
console.log(myobj.var1);
myobj.var1 = 'world';
console.log(myobj.var1);

Aside from that, your code appears solid. Remember, there are multiple approaches to achieve the same result in programming, and it's good practice to experiment with different methods. While coding for fun, it's beneficial to also learn efficient techniques for optimizing your code in production environments.
