call two functions synchronously in javascript

You can call two functions synchronously in JavaScript by invoking one function after the other one completes. You can achieve this using simple function calls.

index.tsx
function firstFunction() {
   // do something here
}

function secondFunction() {
   // do something here
}

firstFunction();
secondFunction();

This will execute the first function and then immediately execute the second function.

If you want to wait until the first function completes before executing the second function, you can use a callback function.

index.tsx
function firstFunction(callback) {
   // do something here and call the callback function
   callback();
}

function secondFunction() {
   // do something here
}

firstFunction(function() {
   secondFunction(); // call second function after first function is complete
});

In this example, the second function is called inside the callback function of the first function. This ensures that the second function is called only when the first function has finished executing.
