我们需要编写一个包含两个字符串的JavaScript函数,并检查第一个字符串是否以第二个字符串开头
例如-
If the two strings are: “Disaster management report” “Disas” Then our function should return true
让我们为该函数编写代码-
const first = 'The game is on'; const second = 'The'; const startsWith = (first, second) => { const { length } = second; const { length: l } = first; const sub = first.substr(0, length); return sub === second; }; console.log(startsWith(first, second));
输出结果
控制台中的输出将为-
true
