JavaScript中循环代码的问题

Question

我在JavaScript学习循环与for循环，我有这个代码(j)，不与我一起工作，我不知道为什么?

let start = 1;
let end = 6;
let breaker = 2;
for (let i = start; i <= end; i++) {
console.log(i);
for (let j = breaker; j <= end; i++) {
console.log(j);
}
}

Answer 1

您永远不会增加j，因此您会得到无限循环，尝试替换

for(let j = breaker; j <= end; i++)

使用

for(let j = breaker; j <= end; j+=1)

Answer 2

您在inner loop中更改了i和j

let start = 1;    
let end = 6;    
let breaker = 2;

for (let i = start; i <= end; i++) 
{
console.log("i => ", i);
for(let j = breaker; j <= end; j++)
{
console.log("j => ", j);
}
}
