Essentially, it creates the equation "a + b = c". However, I need to create "a + b = c" instead.
HTML:
<div class="container">
<span id="b__value">+b</span>
<span id="c__value">=c</span>
</div>
JS:
const valueContainer = document.getElementsByClassName('timer__value')[0];
let newSpan = document.createElement('span');
newSpan.id = 'testId';
newSpan.innerHTML += "77";
valueContainer.insertBefore(newSpan, valueContainer.firstChild);
