A synchronous call in JavaScript is a function call that blocks the execution of the code until it completes.
Synchronous calls wait for the function to finish before moving on to the next line of code.
They can cause the program to become unresponsive if the function takes a long time to complete.
Example: Using the 'fetch' API to make a synchronous call to a server.
To call multiple APIs and fetch data sequentially, use asynchronous calls and handle responses in order.
Use asynchronous calls to make API requests in parallel
Handle responses in order to ensure data is fetched sequentially
Use promises or callbacks to manage the flow of data retrieval
