Javascript finds the sum of values ​​from n to m

Implementation idea:

• Find n to The sum of m values ​​is to find the value of n...m, that is, the cumulative result of the range from n to m

• You can use the for loop to control the cumulative range, fromi= n, i<br>

• In the for loop body, use = for cumulative calculation

Implementation code:

function sum(n,m){
	var sum=0;
	for(var i=n;i<=m;i++){
		sum+=i;
	}
	console.log(sum);
}

When n is 1 and m is 2, 3, 4, 5, the cumulative sum of values ​​from n to m:
