How do I turn a string in dot notation into a nested object with a value – JavaScript?
Let’s say the following is our string in dot notation −
const keys = "details1.details2.details3.details4.details5"
And the following is our array −
const firsName = "David";
To turn into a nested object, use the concept of split(‘.’) along with map().
Example
Following is the code −
const keys = "details1.details2.details3.details4.details5" const firsName = "David"; var tempObject = {}; var container = tempObject; keys.split('.').map((k, i, values) => { container = (container[k] = (i == values.length - 1 ? firsName : {})) }); console.log(JSON.stringify(tempObject, null, ' '));
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo227.js.
Output
The output is as follows −
PS C:\Users\Amit\JavaScript-code> node demo227.js { "details1": { "details2": { "details3": { "details4": { "details5": "David" } } } } }
