word 0 = "Zero" word 1 = "One" word 2 = "Two" How would I condense a pattern-matching function like this one into a single line?
I tried word 0 = "Zero" word 1 = "One" word 2 = "Two", but that didn't work.

SQL pattern matching allows you to search for patterns in data if you don't know the exact word or phrase you are seeking. This kind of SQL query uses wildcard characters to match a pattern, rather than specifying it exactly. For example, you can use the wildcard "C%" to match any string beginning with a capital C.
Pattern matching in computer science is the checking and locating of specific sequences of data of some pattern among raw data or a sequence of tokens. Unlike pattern recognition, the match has to be exact in the case of pattern matching.
Pattern matching is a technique where you test an expression to determine if it has certain characteristics. C# pattern matching provides more concise syntax for testing expressions and taking action when an expression matches.
What Is Pattern Matching? Pattern matching is a feature that is commonly found in functional programming languages. According to Scala documentation, pattern matching is “a mechanism for checking a value against a pattern. A successful match can also deconstruct a value into its constituent parts.”
It's a strange requirement to write a function in a single line. Anyway, case could be helpful there too.
word x = case x of {0 -> "Zero"; 1 -> "One"; 2 -> "Two"} Use semicolons:
word 0 = "Zero"; word 1 = "One"; word 2 = "Two" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
