I want to copy the values from matrixA into matrixB and then add a new element to each array in matrixB.
let number = 100;
matrixA = [
[1, 2],
[3, 4]
];
matrixB = [
[1, 2, 100],
[3, 4, 100]
];
Currently, my code looks like this:
for (let n in matrixB){
matrixB[n] = matrixA.slice();
}
However, I am encountering difficulties in adding the "number = 100"
Kindly refer to the code snippet provided below for implementation.
const matrixA = [
[1, 2],
[3, 4]
];
const number = 100;
const matrixB = matrixA.map(arr => [...arr, number]);
console.log(matrixB);Here are a couple of ways to achieve the desired result:
console.time('example');
const array1 = [[1, 2], [3, 4]], array2 = [];
for(let arr of array1){
array2.push([...arr, 100]);
}
console.log(array1); console.log(array2); console.timeEnd('example');Another approach would be:
console.time('example');
const array1 = [[1, 2], [3, 4]], array2 = array1.map(arr=>[...arr, 100]);
console.log(array1); console.log(array2); console.timeEnd('example');Incorporating a jquery carousel to showcase images within a dynamically updated list has proven fruitful initially.
