js create disctionary in javascript

In JavaScript, we can create a dictionary using an object literal or by using the Object constructor method. Here's an example using object literal:


index.tsx
// create an empty dictionary object
let dict = {};

// add key-value pairs to the dictionary
dict['apple'] = 1;
dict['banana'] = 2;
dict['orange'] = 3;

// print the dictionary object
console.log(dict); // {apple: 1, banana: 2, orange: 3}
240 chars
11 lines

Alternatively, we can use the Object constructor method to create a dictionary as follows:


index.tsx
let dict = new Object();

// add key-value pairs to the dictionary
dict['apple'] = 1;
dict['banana'] = 2;
dict['orange'] = 3;

// print the dictionary object
console.log(dict); // {apple: 1, banana: 2, orange: 3}
213 chars
10 lines

In both cases, we first create an empty object, and then add key-value pairs to the dictionary by specifying the key and its associated value using square brackets. We can then access the values in the dictionary using their respective keys.
