Tests:

  • Concatenation

     
    for (let i = 0; i < 10000; i++){
        let s = "";
        for (let j = 0; j < 4; j++){
            s += obj[j] + " - "; 
        }
        s = s.substring(0,s.length - 3);
    }
    ​

  • Template strings

     
    for (let i = 0; i < 10000; i++){
        let s = `${obj[0]} - ${obj[1]} - ${obj[2]} - ${obj[3]}`;
    }

  • Concatenating strings with template strings

     
    for (let i = 0; i < 10000; i++){
        let s = "";
        for (let j = 0; j < 2; j++){
            s += obj[j] + " - "; 
        }
        s += `${obj[2]} - `;
        s += `${obj[3]}`;
    }

  • Concatenation without substring call

     
    for (let i = 0; i < 10000; i++){
        let s = obj[0] + " - " + obj[1] + " - "  + obj[2] + " - " + obj[3];
    }
