Ruby

Ruby is an expressive, readable language with clean syntax and strong built-in enumerable methods that make array and hash manipulation concise. It is less common in technical interviews than Python, JavaScript, or Java, but it is a valid choice if you use it professionally and are comfortable with it. One practical consideration is that Ruby solutions on LeetCode are sometimes slower than equivalent solutions in compiled languages, which can occasionally cause timeout issues on harder problems. Use Ruby if it is your strongest language, but be aware of this limitation.
