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);
}

 
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]}`;
}

 
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]}`;
}

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

Concat

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

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

Template

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

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