i passed as a props an array of strings an JSX but there is an error message "Missing "key" prop for element in arrayeslintreact/jsx-key "
<Sec1Header
MainText={[
"Your ",
<span className='text-red-400'>
Trusted
</span>,
" Development Partner",
]}
/>
I'm doing all of that to just try to color the text "Trusted" with different colors and not change the div dynamic
You're passing your props in correctly, it's the react/jsx-key ESLint rule that's generating that message. You just need to add a key prop to that <span> tag:
<Sec1Header
MainText={[
"Your ",
<span key="coloredText" className="text-red-400">
Trusted
</span>,
" Development Partner",
]}
/>
Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity...

But as one comment suggested, I would also convert that colored text into its own separate child component.
