我的代码:
const sumAll = function(a, b) {
const arr = [];
if (a < b) {
while (a <= b) {
arr.push(a++);
}
} else if (b < a) {
while (b <= a) {
arr.push(b++);
}
} else {
arr.push(a);
}
if (a < 0 || b < 0) {
return “ERROR”;
} else if (typeof a !== NaN || typeof b !== NaN) {
return “ERROR”;
}
return arr.reduce((a, b) => a + b);
}
module.exports = sumAll
const sumAll=函数(a,b){
常数arr=[];
if(a
const sumAll = function (x, y) {
if (x > 0 && y > 0 && typeof x === 'number' && typeof y === 'number') {
var valorx = x;
var valory = y;
var total = 0;
if (x < y) {
for (var i = valorx; i <= valory; i++) {
total += i;
}
return total;
} else if (x > y) {
for (var i = valory; i <= valorx; i++) {
total += i;
}
return total;
}
} else {
return 'ERROR'
}
}
module.exports = sumAll
const sumAll=函数(x,y){
如果(x>0&&y>0&&typeof x=='number'&&typeof y=='number'){
var valorx=x;
var valory=y;
var合计=0;
if(x 对于(var i=valory;我请不要仅将代码作为答案发布,还要解释代码的作用以及它如何解决问题。带有解释的答案通常更有帮助,质量更好,并且更有可能吸引更多的选票。
