如何将零前导数字(pin)正确转换为字符串[重复]

如何将007514012900等数字转换成字符串?

我怎么得到 pinToStr 返回 '0746' 是吗?

//incorrect output
var pin = 0746;
var pinToStr = pin.toString()
console.log(pinToStr); //486


//correct output
var pin1 = 7460;
var pinToStr1 = pin1.toString()
console.log(pinToStr1); //7460

//incorrect output

let pin = 0746;
let pinToStr = pin.toString()
console.log(pinToStr); //486

//correct output
let pin1 = 7460;
let pinToStr1 = pin1.toString()
console.log(pinToStr1); //7460
