How to use a Loop In Javascript
This approach involves iterating over the arrays simultaneously using a loop and pushing paired elements into a new array.
Example: In this example, we define a function zipArrays that takes two arrays arr1 and arr2 as arguments. We initialize an empty array result to store the zipped elements. Then, we iterate over the arrays using a loop, pushing paired elements [arr1[i], arr2[i]] into the result array. Finally, the zipped array is returned.
function zipArrays(arr1, arr2) {
let result = [];
for (let i = 0; i < Math.min(arr1.length,
arr2.length); i++) {
result.push([arr1[i], arr2[i]]);
}
return result;
}
const array1 = [1, 2, 3];
const array2 = ['a', 'b', 'c'];
const zippedArray = zipArrays(array1,
array2);
console.log(zippedArray);
Output
[ [ 1, 'a' ], [ 2, 'b' ], [ 3, 'c' ] ]
How to Create Zip Array in JavaScript ?
Working with arrays in JavaScript often requires merging or combining multiple arrays into a single structure. One common operation in array manipulation is known as “zipping,” where corresponding elements from multiple arrays are paired together to create a new array.
Example:
Input:
let a = [1, 2, 3]
let b = [a, b, c]
Output: [[1, a], [2, b], [3, c]]
