字符串拼接
双引号配合单引号做拼接练习
let num = 100; // let x = "我有" + num*2 + "块钱"; // let x = "我说:'小明身上有" + num*3 + "块钱'。"; // let x = "<p>num</p>"; // let x = "<p>" +num*50+ "</p>"; let x = "<p style='" +num+ "px;'></p>"; console.log(x);
模板字符串拼接
let a = 10; let b = 20; // let c = `hhh`+a*b+`ggg` let c = `hhh${a}ggg`; console.log(c);
