What Are TOML and YAML?

TOML and YAML help store simple data. People use them for app settings or game configs. They work like different ways to write notes that computers read.

TOML looks basic. It uses equals signs. For example, player_score = 500. Brackets group things, like [player].

YAML uses colons and spaces. Think player_score: 500. Indents show levels, no brackets needed.

Both formats hold the same info. But styles differ. TOML feels like equations. YAML looks like nested lists.

• TOML shines in short keys.
• YAML fits long lists well.
• Many tools read both for TOML to YAML tasks.

Beginners pick YAML for readability. It spreads out data nicely.
