JavaScript检查string1是否以string2结尾
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-
示例
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
