Non-declaration statements in namespaces are not supported

Rule arkts-no-ns-statements

Severity: error

ArkTS does not support statements in namespaces. Use a function to execute statements.

TypeScript

    namespace A {
        export let x: number
        x = 1
    }

ArkTS

    namespace A {
        export let x: number

        export function init() {
          x = 1
        }
    }

    // Initialization function should be called to execute statements:
    A.init()
