Changing the model values locally without effecting the original model in SAPUI5

I am saving data in a model. Data has been fetched from a service call. I am setting that data on different dropdowns in the view. I am changing that data locally on a few checks and conditions but my values in the original data are also getting changed. How to stop that. I need my original data not to be effected.

    HI Swapnil Garg

    Your code will be helpful!!

    The issue might be because in javascript, the objects & arrays are pass by reference.

    https://stackoverflow.com/questions/13104494/does-javascript-pass-by-reference

    So to rectify your issue, you need to to the below:

    //For Objects
    var mCopiedObject = jquery.extend(true, {}, originalObject);
    
    
    // For Arrays
    var mCopiedArray = jquery.extend(true, [], originalArray);
    
    
    // Now you can manipulate the copied object and arrays which will not affect the original object & array

    BR,
