For each operator plus.
Ruby string equality.
Most operators are actually method calls.
Because it s implemented differently in each class it will behave differently depending on the type of object it was called on.
Many of ruby s built in classes such as string range and regexp provide their own implementations of the operator also known as case equality triple equals or threequals.
With an if statement you can check if something is true.
Then ruby would use object s implementation of which defaults to testing for object identity instead of object contents.
But when you want to check for the opposite not true false.
Comparison operators take simple values numbers or strings as arguments and used to check for equality between two values.
The text within the quote marks is the value of the string this is a simple ruby string literal.
There is a corresponding form of abbreviated assignment operator.
Comparison returns 1 0 1 or nil depending on whether string is less than equal to or greater than other string.
Comparison returns 1 0 1 or nil depending on whether string is less than equal to or greater than other string.
B is interpreted as a plus b where the plus.
For example a plus.
One equals sign in ruby means assignment make sure to use when you want to find out if two things are the same.
Ruby supports a rich set of operators as you d expect from a modern language.
It is not uncommon to need to compare two strings either to assess equality or to find out if one string is higher or lower than the other alphabetically speaking.
If the strings are of different lengths and the strings are equal when compared up to the shortest length then the longer string is considered greater than the shorter one.
A string object in ruby holds and manipulates an arbitrary sequence of one or more bytes typically representing characters that represent human language.
But what if string didn t implement.
If you don t this right you won t get the expected results.
Nil is returned if the two values are incomparable.
If the strings are of different lengths and the strings are equal when compared up to the shortest length then the longer string is considered greater than the shorter one.
Nil is returned if the two values are incomparable.
Method in the object referred to by variable a is called with b as its argument.
Notice that we use two equal symbols to mean equality.
