TypeScript - Lambda

Posted on   |  

TypeScript 支援 Lambda 語法，語法如下： 

(input parameters) => expression
(input parameters) => {statement;}


寫起來就像下面這樣： 

1

var Execute = (cmd: string, ...params: string[]): void =>
        alert(cmd + "(" + params.join(", ") + ")");

Execute("Test", "Param1", "Param2");
