※ 物件導向程式設計-OPP(四)

※ 模板字串（template literal）：

• 使用「``」作為語法，作為字串拼接。
• 呈現多行內容。

const multiLineString = `This is a string
that spans multiple
lines.`
console.log(multiLineString)
/*
This is a string
that spans multiple
lines.
*/

• 可使用${var}嵌套變數和任意表達式。

const a = 5
const b = 10
const result = `The sum of ${a} and ${b} is ${a + b}.`
console.log(result) // The sum of 5 and 10 is 15.

• 調用函數

function greet(name) {
  return `Hello, ${name}`
}

const message = `${greet('Bob')}! How are you?`
console.log(message) // Hello, Bob! How are you?
