how to create a src in javascript including external variables?

Question

assume a for loop .how we can add i in src? extracting src from local storage

for(let i;i<10;i++){
//create an img tag object with IMG name
IMG.src='/project/images/${i}/test.png'
}

Answer 1

There are two options:

1. backticks:

IMG.src = `example.com/images/${i}` 

2. the +:

IMG.src = 'example.com/images/'+i

Both work, but I prefer the first option.
