如何使用类型记录将string[]数组添加到record<string，boolean>格式中？

Question

我有一个字符串数组，我希望保留这些值并创建一个新的数组记录。

对于userValue中的每个值。

示例

 userValue: string[] = ["1111","2222","3333","4444"];


  selectedOptions: Record<string, boolean> = {
    //how to add userValue array into here?
    1111: true, //hardcoded
    2222: true, //hardcoded
    3333: true, //hardcoded
    4444: true //hardcoded
  };

Answer 1

// Create the array of strings
let userValue: string[] = ["1111","2222","3333","4444"];

// Create empty Record
let selectedOptions: Record<string, boolean> = {} as Record<string, boolean>;

// Add the array values into the Record
userValue.forEach(val => {
   selectedOptions[val] = true;
});
