How to filters two arrays with multiple keys and value?

var filteredKeyItems = ['primary','gender','regular','normal']
var filteredValuesItems = ['genreal','M',true]

// Output should be:

filteredKeyItems = ['primary','gender']
filteredValuesItems = ['genreal','M']

Here there is a snippet of the two arrays with the keys and values. How can I filter multiple keys as denoted into the code regular and normal with values true in values arrays. Final output should be as per the denoted into the snippet.

Thanks.

The beauty functional way is:

var filteredKeyItems = ['primary','gender','regular','normal']
var filteredValuesItems = ['genreal','M',true]

function filterKeyItem(keyItem) {
    return keyItem !== 'regular' && keyItem !== 'normal';
}

filteredValuesItems = filteredValuesItems.filter((valueItem, index) => filterKeyItem(filteredKeyItems[index]));
filteredKeyItems = filteredKeyItems.filter(filterKeyItem);

console.log('filteredKeyItems', filteredKeyItems);
console.log('filteredValuesItems', filteredValuesItems);

To improve performance a bit, you can use a simple for loop with filling result arrays.

we can do this also by follow

    var filteredKeyItems = ['primary','gender','regular','normal']
    var filteredValuesItems = ['genreal','M',true]


    let filterTwo=[]
    let filterOne=filteredKeyItems.filter((element,index)=>{
     
      //we can assign condition here
    if(element=="primary" || element=="gender" ){
       filterTwo.push(filteredValuesItems[index])
      return  element}}  )
   
    console.log(filterOne)
    console.log(filterTwo)
