我们需要编写一个JavaScript函数,该函数接受两个字符串,即string1和string2,并确定string1是否以string2结尾。
例如-
"The game is on" Here, "on" should return true
而,
"the game is off" Above, “of" should return false
让我们为该函数编写代码-
const first = 'The game is on'; const second = ' on'; const endsWith = (first, second) => { const { length } = second; const { length: l } = first; const sub = first.substr(l - length, length); return sub === second; }; console.log(endsWith(first, second)); console.log(endsWith(first, ' off'));
输出结果
控制台中的输出将为-
true false
