# Ruby vs Node.js
____
## ARGV
____
### Creation ARGV
___
####Ruby
```ruby
arg = ARGV
p arg # []
```
____
####Nodejs
```node
let arg = process.argv
console.log(arg) // ['C:\\Program Files\\nodejs\\node.exe','C:\\Project\\NODE\\RubyVsNodeJs\\app']
```
____
____
###Get one argv
####Ruby
```ruby
ruby app.rb one 2 3 hi!
```
```ruby
p ARGV[0] # "one"
```
```ruby
ruby app one 2 3 hi! # not valid ... -- app (LoadError)
```
####Nodejs
```node
node app.js one 2 3 hi!
```
or
```node
node app one 2 3 hi! // valid
```
```node
console.log(process.argv[2]) // one
```
____
____
###Operator if
####Ruby
```ruby
a,b = ARGV[0],ARGV[1]
```
```ruby
ruby app.rb 1 2
```
```ruby
p (if a > b then a else b end) # "2"
```
or
```ruby
p a > b ? a : b # "2"
```
____
####Nodejs
```node
// node app.js 1 2
arg = process.argv
let a = arg[2]
let b = arg[3]
let out = a + ' ' + b
console.log(out) // 1 2
if (a > b) {
console.log(a)
} else {
console.log(b)
} // 2
let c = (a > b) ? a : b
console.log(c) // 2
```
___
###Operator if
__!!!BANG!!!__
___
####Ruby
```ruby
#ruby app.rb 8 44444
a,b = ARGV[0],ARGV[1]
print a,' ', b ,"\n" # "8" "44444"
p (if a > b then a else b end) # !!! "8" !!!
p a > b ? a : b # !!! "8" !!!
p a.class # String
p b.class # String
```
```ruby
#ruby app.rb 8 44444
a,b = ARGV[0].to_i,ARGV[1].to_i
print a,' ', b ,"\n" # 8 44444
p a.class #Integer
p b.class #Integer
p a > b ? a : b # 44444
```
####Nodejs
```node
// node app.js 8 44444
a = arg[2]
b = arg[3]
console.log(out) // 8 44444
c = (a > b) ? a : b // !!!!!!!!
console.log(c) // !!! 8 !!!
console.log(typeof a) // string
console.log(typeof b) // string
```
```node
// node app.js 8 44444
a = +arg[2]
b = +arg[3]
console.log(typeof a) // number
console.log(typeof b) // number
c = (a > b) ? a : b
console.log(c) // 44444
```
