I am in need of several arrays:
array 1 = [1,9,17,25,33,41];
array 2 = [2,10,18,26,34,42];
and so on.
Each array should increment by 8 from the previous one.
I want to create this dynamically using JavaScript functions.
I am in need of several arrays:

and so on.

I want to create this dynamically using JavaScript functions.
var initialValue = 5;
var increment = 8;
var length = 5;
function createIncrementArray(initialValue, increment, length) {
for (var j = 0, array = []; j < length; j++) {
array.push(initialValue);
initialValue += increment;
}
return array;
}
console.log(createIncrementArray(initialValue, increment, length));Is this the kind of code you're looking for?
for(let i = 1; i<10;i++){
eval("let array" + i + " = [" + i + "];");
for(let j = 1; j<10; j++){
eval("array" + i + ".push(array" + i + "[array" + i + ".length] + 8);");
}
}Give dynamic variable names a shot!
let count = 2;
let startValue = 5;
let difference = 8;
let length = 5;
for(let i=1; i<=count; i++) {
window['array'+i] = createArray(i,difference,length);
alert(window['array'+i]);
}
function createArray(startValue) {
let newArray = [];
for (let j = 0, val = startValue; j < length; j++) {
newArray.push(val);
val += difference;
}
return newArray;
}
Even though the answer has already been approved, I thought it would be beneficial to include the implementation in ES6 syntax here.
const [start, step, length] = [5, 8, 5], temp = start;
const array = Array(length).fill(start)
.map((value, index) => (index) ? temp += step : value);
