Is there a way to achieve the specified outcome in JavaScript? I attempted to find a method for it on MDN but was unsuccessful.
let a, b
let allNumbers = []
for (a = 10; a < 60; a = a + 10) {
for (b = 1; b <= 3; b++) {
allNumbers.push(a + b)
}
}
The expected result is an array within the allNumbers array:
[[11,12,13], [21,22,23], [31,32,33], [41,42,43], [51,52,53]]
To efficiently solve this problem, one approach is to create a temporary array within the outer loop and populate it with elements from the inner loop. Once the inner loop completes, append the temporary array to the main array:
let x, y
let allValues = []
for (x = 5; x < 25; x += 5) {
let someValues = [];
for (y = 1; y <= 4; y++) {
someValues.push(x + y)
}
allValues.push(someValues)
}
console.log(JSON.stringify(allValues))What do you think of this code snippet?
let x, y
const numberArray = []
for (x = 10; x < 60; x = x + 10) {
let partArray = [];
for (y = 1; y <= 3; y++) {
partArray.push(x + y)
}
numberArray.push(partArray)
}
To solve this problem, you must utilize a second array.
let x, y
let allValues = []
for (x = 10; x < 60; x = x + 10) {
secondArray = [];
for (y = 1; y <= 3; y++) {
secondArray.push(x + y);
}
allValues.push(secondArray)
}
console.log(allValues);You can also achieve the same result using a more concise approach with ES6 capabilities.
allValues = []
for (x = 10; x < 60; x = x + 10) {
allValues.push([...Array(3)].map((_, i) => i + x + 1))
}
console.log(allValues);Check out this code snippet:
const newArray = Array(5).fill(1).map((a, i) => Array(3).fill(1).map((a, j) => +`${i+1}${j+1}`));
console.log(JSON.stringify(newArray));To complete this task, you will need to create a new array and add elements to it within the second loop. Once finished, append this array to the final one after the completion of the second loop.
let x, y
let finalArray = []
for (x = 5; x < 30; x = x + 5) {
newArray = []
for (y = 1; y <= 4; y++) {
newArray.push(x + y)
}
finalArray.push(newArray)
}
console.log(finalArray)In order to properly iterate, it is necessary to create a secondary array within the loop. Here is an example of how you can achieve this:
let x, y
let totalValues = []
for (x = 5; x < 30; x = x + 5) {
var temporaryArray = [];
for (y = 1; y <= 4; y++) {
temporaryArray.push(x + y)
}
totalValues.push(temporaryArray);
}
console.log(totalValues);To add a new array to the existing array called allNumbers, follow these steps:
...
let newArray = []
for (index = 1; index <= 3; index++) {
newArray.push(existingElement + index)
}
allNumbers.push(newArray)
