The provided code snippet seems mostly correct for its purpose, but there is one suggestion for improvement:

if (n !== undefined && n.properties.node_data && n.properties.node_data.tool_lib_id) {
  extra.value.current_tool_id = n.properties.node_data.tool_lib_id;
}

In JavaScript/TypeScript, undefined cannot be used directly to check for truthiness due to coercion rules. Using strict equality checks (!==) or ensuring that n is defined prevents unnecessary comparisons with other falsy values. This change improves clarity and correctness.

Here's the optimized version of the function:

const sourceChange = (node_id: string) => {
  base_form_data.value.node_id = node_id
  const n = source_node_list.value.find((n: any) => n.id === node_id);
  if (n && n.properties.node_data?.tool_lib_id) {
    extra.value.current_tool_id = n.properties.node_data.tool_lib_id;
  }
  // ... rest of the original function ...
};

This modification adds a conditional check before accessing n.type after filtering source_node_list. The use of optional chaining operator (?.) makes the expression safer by avoiding errors when n.properties.node_data is not available.
