Answer 1

Mistakes

1. Try to write whole thing inside
window.onload=()=>{
//Your code
}

2. Use innerText instead of text()
option.innerText = "=" ;

3. to use .text it should be .text = "=" instead of .text()

code :

window.onload=()=>{
let tempSel=document.createElement("select");
tempSel.classList.add("form-control");
tempSel.size=1;
tempSel.name='f**k';
let option = document.createElement("option");
option.value = "0";
option.innerText = "=";
tempSel.appendChild(option);
document.body.append(tempSel);

}

Watch your language

Answer 3

It says text is not a function. Probably you should search a bit about what properties are available option element.

You just can't add any property or function and expect it work.
