how to do x plus y in javascript

To do x plus y in JavaScript, you can use the + operator. Here is an example:

index.tsx
let x = 5;
let y = 10;
let result = x + y;
console.log(result); // Output: 15
78 chars
5 lines

In this example, we declare two variables x and y with values of 5 and 10 respectively. We then use the + operator to add the two variables and assign the result to a new variable result. Lastly, we log the value of result to the console which outputs 15.
