Destructuring

Definition

Destructuring is a syntax feature that allows you to unpack values from arrays or properties from objects into distinct variables. It provides a concise way to extract data without needing multiple assignment statements.

Where you hear it

During code reviews, when discussing modern JavaScript or Python syntax, or when refactoring data-heavy functions.

Examples

• You can use destructuring to extract specific fields from a user object into local variables.
• Destructuring an array allows you to assign its elements to individual variables in one line.
