# Destructuring parameter declarations are not supported Rule ``arkts-no-destruct-params`` **Severity: error** ArkTS requires parameters to be passed directly to the function, and local names to be assigned manually. ## TypeScript ``` function drawText({ text = "", location: [x, y] = [0, 0], bold = false }) { console.log(text) console.log(x) console.log(y) console.log(bold) } drawText({ text: "Hello, world!", location: [100, 50], bold: true }) ``` ## ArkTS ``` function drawText(text: String, location: number[], bold: boolean) { let x = location[0] let y = location[1] console.log(text) console.log(x) console.log(y) console.log(bold) } function main() { drawText("Hello, world!", [100, 50], true) } ```
