Q1:
This calculator takes values that could be written in a browsers route path as a single string. It then returns the result as a number (or an error message).
Route paths use the '/' symbol so this can't be in our calculator. Instead we are using the '$' symbol as our divide operator.
You will be passed a string of any length containing numbers and operators:
| #!/bin/bash | |
| yum update -y | |
| yum install -y httpd | |
| systemctl start httpd | |
| systemctl enable httpd | |
| TOKEN=$(curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600") | |
| EC2_AZ=$(curl -H "X-aws-ec2-metadata-token: $TOKEN" http://169.254.169.254/latest/meta-data/placement/availability-zone) |
| // Module using the Module Design Pattern | |
| var Module = (function() { | |
| // Private variable | |
| var privateVariable = "I am a private variable"; | |
| // Private function | |
| var privateFunction = function privateFunction() { | |
| console.log("This is a private function"); | |
| } |
