difference between list and set in java code example
Example 1: difference between java and javascript
java is virtualised and compiled while javascript isn't.
javascript and java aren't that similar apart from beign
both OOP.
Example 2: List vs Set
List > Ordered and Indexed Collection, May contain duplicates
Set > Collection of Unique values, not ordered, no indexing
Example 3: Ruby difference between for and .each
# They are both similar in function, however the for loop will retain a variable.
# FOR Example:
nums = [1,2,3]
for n in nums
puts n
end
=> 1 2 3
# If you ask what is n, n outputs the last assignment from the function.
n => 3
# EACH Example:
nums.each do |i|
puts i
end
=> 1 2 3
# If you ask what is i.
i => NameError (undefined local variable or method `i' for main:Object)
