Answer 1

数字末尾有ascii值为8236的隐藏字符您可以通过

验证它们

console.log(numberA.length, numberB.length) // 14, 16
console.log(numberA.split("").map(char => console.log(char.charCodeAt(0))))
console.log(numberB.split("").map(char => console.log(char.charCodeAt(0)))) // this will give two 8236 ascii value at the last of the string
