How to use the idyll-ast.removeProperty function in idyll-ast

// $ExpectType [string, [PropType, PropData]] || Property
getProperties(ast[1])[0];
// $ExpectType [string, [PropType, PropData]][] || Property[]
getPropertiesByType(["h1", [], []], "variable");

// $ExpectType Node[] || AST
removeNodesByName(ast, "h1");

// $ExpectType Node
setProperty(ast[0], "prop", 9);

// $ExpectType Node
setProperties(ast[1], { prop1: ["expression", "x"], prop2: 3 });

// $ExpectType Node
removeProperty(ast[0], "prop1");
