I have to convert two arrays into a single array base on given below condition. a= ["dry chapati", "dry chapati", "dry chapati"] b = ["chapati", "less fat", "no oil"];

I want to convert a and b to as below

c = ["dry chapati" : "chapati", "less fat", "no oil"]

I am trying it as below but not getting desired result as c

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"];

let r = [];
for(let i=1; i<recipe.length; i++){
    if(recipe[i] == recipe[i+1]){
        recipe[i] = tags
        // console.log(recipe);
    }
}

Please help to find a solution.

    Your `c` is not a valid JavaScript object or array... – Cerbrus Oct 19 '22 at 12:10

    Does this answer your question? [Get all unique values in a JavaScript array (remove duplicates)](https://stackoverflow.com/questions/1960473/get-all-unique-values-in-a-javascript-array-remove-duplicates) – Valeriu Ciuca Oct 19 '22 at 12:19
  • Needs more details. On what basis we need to make calculations ? What will be the relations between `a` and `b` to assign the tags ? – Debug Diva Oct 19 '22 at 15:39
  • This question must have been asked many times before but this one is extremely badly worded and the OP doesn't even have a valid desired result. OP should do more research and will get better answers than asking this again like this. – NeilG Oct 20 '22 at 00:28

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"]; 

let array3 = [...new Set(recipe.concat(tags) )];
console.log(array3);

  • Thanks, this will work, but here its a different scenario that it must print exactly the same as ["dry chapati" : "chapati", "less fat", "no oil"] – Alok007 Oct 19 '22 at 12:29

let arr1 = ["dry chapati", "dry chapati", "dry chapati"];
let arr2 = ["chapati", "less fat", "no oil"];


const merge = (arr1, arr2) => {
  const res= [arr1[1]];
  arr1.forEach((arr,i) => 
    res.push(`${arr2[i]}`)
    );
    return res;
}

console.log(merge(arr1,arr2));

Just use merge

$a1=array("red","green");
$a2=array("blue","yellow");
print_r(array_merge($a1,$a2));

Try using the spread syntax.

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"];

let result = [...recipe, ...tags];
let result2 = [];
result2.push(...new Set(result));
console.log(result2);

This will give you the result you want.

You question is not clear as what you want to achieve but according to my understanding of the problem. Give below are two possible ways.

 /*If you want to achieve something like
  let c = [{'dry chapati': 'chapati'}, {'dry chapati': 'less fat'}, {'dry chapati': 'no oil'} ]
  */
  let thirdArray = [];
  for (let i = 0; i < recipe.length; i++) {
    let dish = {
      [recipe[i]]: tags[i],
    };
    thirdArray.push(dish);
  }

  /*If you want to achieve something like
  let c = [{'dry chapati': ['chapati', 'less fat', 'no oil']}. {...}]
  */
  let fourthArray = [];

  for (let i = 0; i < tags.length; i++) {
    let secondDish = {
      [recipe[i]]: [tags],
    };
    fourthArray.push(secondDish);
  }

You can use LINQ. Zip in jQuery, you can add (https://github.com/multiplex/multiplex.js) LINQ library JS in your script file and try this code.

var arr1 = [1, 2, 3, 4]; var arr2 = ["A", "B", "C", "D"];

var res = arr1.zip(arr2, function(a, b){ return {Num:a, Letter:b} });
