ES6---模板字符串

1,之前JavaScript输出字符串,通常是:

 $("#result").append(
    "He is <b>"+person.name+"</b>"+"and we wish to know his"+person.age+".That is all" 
    );

大量用到""和+ 不是很方便

模板字符串,用``(反引号)标识,用${ }将变量括起来:

 $("#result").append(
    `He is <b>${person.name}</b>and we wish to know his${person.age}.that is all`
    )

举个例子

 var x=88;
var y=100;
console.log(`x=${++x},y=${x+y}`);//x=89,y=189
