控制流程语句: Block 块语句; break; continue; empty 空语句; if...else; switch; throw; try...catch

函数和类: function; function*; async function; return; class; function arguments; getter; setter; =>箭头函数

循环与迭代: do...while; for; for each...in; for...in; for...of; for await...of; while

其它语句: debugger; export; import; import.meta; label; with
