The 18-year-old has been on the bench for the Magpies' first team and started some of their pre-season friendlies.
"I'm really looking forward to it. It's a massive difference and it takes some getting used to," he told BBC Sussex.
"I'll take this experience back with me and say 'let's not come back here, let's play in the Premier League'."
He added: "But first-team football is where everything happens. The best thing for me was to come on loan and I'm grateful Crawley have taken me."
