Javascript variable to razor variable

how can i change my javascript variable to a razor variable in mvc.
let data = JSON.parse(this.responseText).data.Table;
this is my javascript variable.

what is razor variable?

i want to use this variable in foreach loop in mvc

if the data is an Object, then you can’t use forEach. If data is an array, then you can use it. What is type data?
If it is an Object, than you can use Object.keys to loop over the keys.

let obj = {a: 1, b: 2};
Object.keys(obj).forEach(e => console.log(obj[e])) // 1, 2
