Hiragana and Katakana shortly explained

Hiragana and Katakana are two of the three writing systems used in the Japanese language, the third being Kanji, which are Chinese characters adopted into the Japanese writing system. Hiragana and Katakana, on the other hand, are both phonetic scripts used to write the Japanese language.

Hiragana is used primarily to write native Japanese words and grammatical elements, such as particles, verb endings, and adjectives. It is also used for children's books and for writing words that do not have a corresponding Kanji.

Katakana, on the other hand, is used primarily to write foreign loanwords, such as "computer" (コンピューター), "coffee" (コーヒー), and "hamburger" (ハンバーガー). It is also used for emphasis, onomatopoeic words, and for words that are considered technical or scientific.

In general, both Hiragana and Katakana are essential for learning and using the Japanese language. Mastery of Hiragana and Katakana is often the first step for beginners to start reading and writing in Japanese, and is a prerequisite for learning Kanji.
