How exclude string part from main string that has in array by javascript

December 21, 2021

I have string that exist in array as follow

getid Array [
  "E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2",
]

I want to exclude this part E8R52y6dD8XI3shXhnhS9pVzUpe2 from that ,

actually E8R52y6dD8XI3shXhnhS9pVzUpe2 this is user.uid .
this is two user id combine id "E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2"
this combine id exist in arrays.
so many combine id will has in this array.
I want to exclude user.uid E8R52y6dD8XI3shXhnhS9pVzUpe2 from all combine id .
if exclude user.uid , there will be remain one id part in this array.
I want to get this remain part of id value to use.

let userid = E8R52y6dD8XI3shXhnhS9pVzUpe2
let combineId = ["E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2","E8R52y6dD8XI3shXhnhS9pVzUpe26Lh5bHrzCSvI2bmoMv7KuduMGwe2","E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2"]

// this is value what i want
let remainIdinArray = ["6Lf5bHwzCSbI2bmoMv7KuduMGwe2","6Lh5bHrzCSvI2bmoMv7KuduMGwe2","6Lf5bHwzCSbI2bmoMv7KuduMGwe2"]

how can do that.
thanks

>Solution :

You can use the map and the slice!


    let userid = "E8R52y6dD8XI3shXhnhS9pVzUpe2";
    let combineId = [
      "E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2",
      "E8R52y6dD8XI3shXhnhS9pVzUpe26Lh5bHrzCSvI2bmoMv7KuduMGwe2",
      "E8R52y6dD8XI3shXhnhS9pVzUpe26Lf5bHwzCSbI2bmoMv7KuduMGwe2"
    ];
    
    let remainIdinArray = combineId.map((id) => id.slice(-userid.length));
    
    console.log(remainIdinArray);
