instruction

Write a JavaScript function `twoSum(nums, target)` returning the indices [i, j] (i<j) of the two numbers that add to target. Exactly one solution exists. Return only the code in a ```js block.

final output

```js
function twoSum(nums,target){const m=new Map();for(let i=0;i<nums.length;i++){const c=target-nums[i];if(m.has(c))return [m.get(c),i];m.set(nums[i],i);}return [];}
```
