store result of function in variable in javascript

To store the result of a function in a variable in JavaScript, you can assign the function call to a variable. Here's an example:

index.tsx
function multiply(x, y) {
  return x * y;
}

let result = multiply(3, 5);
console.log(result); // Output: 15
109 chars
7 lines

In the above example, the multiply function takes two parameters x and y and returns their product. We then call the multiply function with arguments 3 and 5 and assign the resulting value to a variable named result. Finally, we log the value of result to the console, which should output 15.
