Serverless JavaScript Projects 2.4: Connect the Two Lambdas

This video tutorial demonstrates how to connect two AWS Lambda functions, integrate a front-end application using jQuery, and retrieve data from a third-party API. It covers creating functions to get location and weather data, configuring CORS for API access, and planning the next steps for front-end integration. The tutorial also discusses deploying applications using NPM and Surge.

What is the primary purpose of connecting two Lambda functions in this tutorial?

• To simplify code structure

• To enhance database security

• To enable data exchange between functions

• To reduce execution time

Which feature is used to handle errors in the Lambda functions?

• Event Loop

• Callback

• Promise

• Async/Await

What is the role of the third-party API 'typify' in the front-end setup?

• To handle database connections

• To manage user sessions

• To retrieve external IP address

• To fetch user location

Which JavaScript library is used for the front-end setup in this tutorial?

• jQuery

• Vue.js

• Angular

• React

What is the purpose of the 'getLocation' function?

• To manage user authentication

• To obtain geographical location based on IP

• To retrieve user preferences

• To fetch weather data

What command is used to deploy the application locally?

• npm start

• npm test

• npm build

• npm run deploy

What issue does the tutorial address when dealing with AWS Lambda and API Gateway?

• Latency problems

• Data encryption

• CORS configuration

• Function timeout

What is the solution to the CORS issue mentioned in the tutorial?

• Enable CORS in the API Gateway

• Use a different API

• Disable security settings

• Change the Lambda function code

What data is being verified for correctness in the final section?

• API response time

• Location data

• Weather data

• User credentials

What platform is suggested for deploying front-end applications?

• Heroku

• AWS S3

• Netlify

• Surge
