I am interested in implementing the following scenario:
var A = ["Jon","Brad","Rachel"];
var B = ["Male","Male","Female"];
var C = [
{"Jon","Male"},
{"Brad","Male"},
{"Rachel","Female"}
]Can you guide me on how to retrieve var C using javascript?
If you're looking to combine two arrays without sorting them, there are various libraries such as Lodash that offer methods for achieving this task.
An alternative way to achieve this is by creating a custom function like the one provided below:
function mergeArrays (arr1, arr2) {
if (arr1.length !== arr2.length) return [];
return arr1.map(function (item, index) {
return [item, arr2[index]];
});
}
It's worth mentioning that using {"Rachel", "Female"} kind of syntax is not valid in JavaScript. Instead, arrays should be enclosed in square brackets [], while objects are enclosed in curly braces {}.
Instead of using {"Jon","Male"}, I utilized arrays in order to make the content valid.
var D = A.map(function( name, index ) {
return [name, B[index]];
});
let D = {};
for (let j = 0; j < E.length; j++) {
D[E[j]] = F[j];
}
