How to push key as iterative value in js?

Hi i have a two for loop contains checking the each loop length and push into key value pair of array

for (var i=0; i<allTextLines.length; i++) {
        var data = allTextLines[i];
        if (data.length == headers.length) {

            var tarr = [];
            for (var j=0; j<headers.length; j++) 
            {
              
               ****tarr.push({headers[j]:data[j]})****
            }
            
             lines.push(tarr);

        }
        
    }
