What is the method for converting a string[] array to a record<string, boolean> format in typescript?

I have a string array that contains values I want to keep and use to create a new array called Record.

For each value in the userValue array.

For example:

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


  selectedOptions: Record<string, boolean> = {
    //how can I add values from the userValue array here?
    1111: true, //hardcoded
    2222: true, //hardcoded
    3333: true, //hardcoded
    4444: true //hardcoded
  };

Answer №1

// Declare an array of strings
let userInput: string[] = ["apple","orange","banana","grape"];

// Initialize an empty Object
let chosenFruits: Record<string, boolean> = {} as Record<string, boolean>;

// Populate the Object with array values
userInput.forEach(fruit => {
   chosenFruits[fruit] = true;
});
