Solution 1:[1]

If you work with the JavaScript DOM spellcheck property (as opposed to the HTML spellcheck attribute), you need to assign an actual boolean value, not a string.

const inp = document.body.appendChild(document.createElement('input'));
inp.placeholder = "enter line of code";
inp.autocomplete = "off";
inp.spellcheck = false; // not "false" which is a string

Set an attribute instead.

const inp = document.body.appendChild(document.createElement('input'));
inp.placeholder = "enter line of code";
inp.autocomplete = "off";
inp.setAttribute('spellcheck', 'false');
