Sometimes I have code where I have to insert consecutive values. This is a problem with big files. First I make them all the same, after which I increase the value 1 by 1.. Such as:
<div>a1</div>
<div>a1</div>
<div>a1</div>
<div>a1</div>
<div>a1</div>
<div>a1</div>`
becomes:
<div>a1</div>
<div>a2</div>
<div>a3</div>
<div>a4</div>
<div>a5</div>
<div>a6</div>
