Good day programmers, I tried to get the range of a set of numbers and console.log the sum. Sounds simple right?

I tried using
console.log(range(1,200));
And
console.log(Range (1,200);
But I kept getting a reference error: range or Range is not defined.

Then in frustration I tried doing Math.range(1,200) hoping that JavaScript might have a built in range method on it's Math object

Finally I resigned myself to printing the numbers in that range with a for loop and pushing the result to an empty array with the .push method on arrays.

I want to know how I could have done this using the range method. Thanks.

bros in javascript there is nothing like "range()" function ooo but in python their is a range() function

Thought as much

Nope.

range = (start, end) => {
return Array.from({ length: end - start + 1 }, (_, i) => i)
}

range(3,50)


The above is what I can suggest. Which will produce 3 to 50

Maskyy:
range = (start, end) => {
return Array.from({ length: end - start + 1 }, (_, i) => i)
}

range(3,50)

Thanks for this code.

I find it strange that JavaScript doesn't have a built in method for this.

Not actually strange. Every language has a different building community. If it pleased js, they can do a workaround and add the above code as path of their Math method.

But I can still save this code and call the function anytime. More like my own script or library.

I guess that's true.

I guess you are right. I'll start adding code I feel I may need again down the line to a personal library.

//Using for loop function range(min,max){ var result=Number(); for(;min<max+1;min++){ result += min } return result; } console.log(range(2,10))

range = (start, end) => {
return Array.from({ length: end - start + 1 }, (_, i) => i)

Please what is the relationship between what you wrote above and this

console.log(range(1,200))

Maskyy:
range = (start, end) => {
return Array.from({ length: end - start + 1 }, (_, i) => i)
}

range(3,50)

I think this should be the correct function

const range = ( start, stop) => Array.from( { length: ( stop - start ) + 1 }, ( _, i ) => start + i );


console.log(range(3,50));
