Usingfor loopwith index assigned with initial number and increment by 1 until end of the number, and add an index to an array. Here is an example to create an array of sequence numbers from 1 to 50. varnumbers=[];for(vari=1;i<=50;i++) {numbers.push(i);}console.log(numbers); ...
Finally, you can pass a third "step" argument, if you want to change the gap between numbers: Copy to clipboard range(0, 6, 2); // [0, 2, 4] range(10, 12, 0.5); // [10, 10.5, 11, 11.5] You'll notice that the array produced is inclusive of the starting number, but excl...

We are required to write a JavaScript function that takes in an array of numbers sorted in increasing order. Our function should calculate the variance for the array of numbers. Variance of a set of numbers is calculated on the basis of their mean. Mean(M)=(∑n−1i=0arr[i])Mean(M...
