VistasConcatenate elements of an array Javascript
I have a list of hrefs with product data:name and it's id. First of all i removed prod Id that i'll use as separate variable. After this, the remained part of href should be used as the product name.
var prodHref = document.querySelectorAll('.widget-products-list-item-label');
var allHref = [];
for(var i=0;i<prodHref.length;i++){
allHref.push(prodHref[i].href.split('/')[5])
}
var prodName = [];
for(var i=0;i<allHref .length;i++){
prodName.push(allHref [i].slice(0, -1))
}
var prodNameNew=[];
for(var i=0;i<prodName .length;i++){
prodNameNew.push(prodName[i].slice(0, -1))
}
So, the final result is on the attached screen. N
How i have concatenate all the elements of each array in order to get new arrays in the following format: Nokia G20 4 64 Albastru, Motorola G60 gri etc Thank You

You want to capitalize the items of the inner arrays and then join them by space.
One way to do it is:
let result = arr.map(a => a.map(capitalize))
.map(a => a.join(" "))
where capitalize should be a function that takes a string and returns a string with first letter in upper case if possible.
You can find this in answers for the more specific SO question:
How do I make the first letter of a string uppercase in JavaScript?

Instead of 3 separate loops, we can get the substring based on single iteration only using Array.map() along with String.slice().
const prodHref = [{
href: "https://abc/def/ghi/alpha/mno"
}, {
href: "https://abc1/def1/ghi1/beta/mno1"
}, {
href: "https://abc2/def2/ghi2/gamma/mno2"
}, {
href: "https://abc3/def3/ghi3/omicron/mno3"
}];
const allHref = prodHref.map((obj) => obj.href.split('/')[5].slice(0, -2));
console.log(allHref);Now you can use Array.join() method to join the result array.
const allHref = ["alp", "be", "gam", "omicr"];
console.log(allHref.join(" "));
