個人總結(jié)
初次接觸JS的代碼和語法膏秫，發(fā)現(xiàn)與其他代碼的語法有相似之處泥兰，根據(jù)題目需求码俩，傳入一個數(shù)，進行判斷蟀拷，返回一個符合要求的字符串。
第①個需求：當給run函數(shù)傳入數(shù)值3時，返回值應為Fizz寿弱。run(3),系統(tǒng)判斷傳入值為3，那么就return Fizz,把Fizz賦值給result變量按灶，通過document函數(shù)打印出來症革，需求實現(xiàn)。
做第②個需求：傳入5鸯旁，返回Buzz噪矛。run(5),判定傳入值為5，返回Fizz铺罢，賦給result艇挨，通過函數(shù)打印出來，第二個需求實現(xiàn)韭赘。
剩下的類似缩滨，判定是某個數(shù)值的倍數(shù)，則傳入的數(shù)值對那個數(shù)進行取余，若余數(shù)為0脉漏，則表示能整除苞冯，符合判斷，返回相應的字符串侧巨，打印舅锄。
