从 object 中的数组中删除除特定项之外的所有项目

Question

Trying to remove all items from the array inside object but getting this error Cannot delete property '0' of [object Array]

object array:

       let tempBrand = [
          {
         name: "Toshiba",
         models:["Toshiba Excite Pro","Toshiba Regza AT300","Toshiba Regza AT1S0","Toshiba Folio 
         100","Toshiba G500","Toshiba AT720"]
         }
        ]

       let tagsData= ["Toshiba Regza AT300","Toshiba Regza AT1S0"]

this is what I'm trying to do.

       for (let i = 0; i < tempBrand.length; i++){
            tempBrand[i].models.length = 0;
            for (let j = 0; j < tempBrand[i].models.length; j++){
                if (tempBrand[i].models[j] !== tagsData[i]) {
                    delete tempBrand[i].models[j];
                }
            }
        }

I am unable to understand exactly what you are trying to achieve but here is my implementation about what I understood from your problem. As you have updated the question here is the updated answer. If you want to persist with the iterative approach you can use that or else as mentioned in the comments you can use es6 methods for functional style of coding.

let tempBrand = [
         {
         name: "Toshiba",
         models:["Toshiba Excite Pro","Toshiba Regza AT300","Toshiba Regza AT1S0","Toshiba Folio 100","Toshiba G500","Toshiba AT720"]
        }
        ]

       let tagsData= ["Toshiba Regza AT300","Toshiba Regza AT1S0"];
 
 for (let i=0 ; i<tempBrand.length;i++)
for(let j=0 ; j<tempBrand[i].models.length;j++){
    if(tagsData.includes(tempBrand[i].models[j]))
    {
      console.log({item : tempBrand[i].models[j]});
      tempBrand[i].models.splice(j, 1); 
     }   
}
console.log({tempBrand})
