1.字串插值

單行和多行字串的直觀表示式插值。 （注意：不要混淆，模板文字最初在ECMAScript 6語言規範草案中命名為“模板字串”） ECMAScript 6

var customer = { name: "Foo"}
var card = { amount: 7, product: "Bar", unitprice: 42}
var message = `Hello ${customer.name},
want to buy ${car.amount} ${card.product} for 
a total of ${card.amount * card.unitprice} bucks ?`
//前後結尾的是右上頓號` 鍵盤tab上面的按鍵，不是單引號',換行不需要換行符
 

ECMAScript 5

var customer = { name: "Foo"};
var card = { amount: 7, product: "Bar", unitprice: 42};
var message = "Hello" + customer.name + ",\n" + "want to buy" + card.amount + " "+ card.product + "for\n" + "a total of" + (card.amount * card.unitprice) + "bucks?";

2.自定義插值

任意方法的靈活表達插值 ECMAScript 6

get`http://example.com/foo?bar=${bar + baz}&quux=${quux}

ECMAScript 5

get(["http://example.com/foo?bar=", "&quux=", ""],bar + baz, quux);

3.原始字串訪問

訪問原始模板字串內容（不解釋反斜槓）。(看不懂) ECMAScript 6

function quux (strings, ...values) {
    strings[0] === "foo\n"
    strings[1] === "bar"
    strings.raw[0] === "foo\\n"
    strings.raw[1] === "bar"
    values[0] === 42
}
quux`foo\n${ 42 }bar`

String.raw`foo\n${ 42 }bar` === "foo\\n42bar"
 

ECMAScript 5

//ES5中沒有對應的表達方式
