Strip vs Squish

Sample

"   hello    world  ".strip
=> "hello    world"

"   hello    world  ".squish
=> "hello world"

What's difference?

Strip

• Ruby method
• Returns the string, remove white spaces only at the leading and trailing

Squish

• Rails method
• Returns the string, first removing all whitespace on both ends of the string, and then changing remaining consecutive whitespace groups into one space each.

How to use squish in ruby without rails?

Very simple

"  hello    world".split.join(" ")
=> "hello world"
