I’m having trouble with my JavaScript code and could really use some help. When I try to run my savePlayer function, I keep getting an error message that says players.push is not a function. This is really frustrating because I thought I was doing everything correctly.
I’m not sure what’s causing this issue. The error suggests that my players variable isn’t being recognized as an array, but I’m pretty confident I declared it properly. Has anyone else encountered this problem before?
I’ve been working on this for a while now and can’t figure out what’s going wrong. Any suggestions or advice would be greatly appreciated. Thanks in advance for your help!
first, double-check you’re actually declaring players as an array - let players = []; or var players = new Array();. easy to think you did but skip that step. also, javascript’s async behavior might be clearing your array before the push happens.
This happens when your players variable gets overwritten or isn’t initialized as an array. I hit this exact bug last year - I’d accidentally reassigned my array to a string or object somewhere else without realizing it. Look for any code doing players = someOtherValue after you declare the array. Also check for scope issues where you think you’re using your array but you’re actually hitting a different variable with the same name. Drop a console.log(typeof players) right before your push to verify it’s still an array. If it shows anything other than ‘object’, there’s your problem.
I hit this exact same error with API data. The problem was I was trying to push to the array before it finished loading from the server response. Check if your players variable is getting populated asynchronously - like from a fetch request or database call. If it is, the timing’s probably off and you’re calling push before the array actually exists. Also make sure you’re not accidentally using the same variable name in a different scope. Try adding console.log(Array.isArray(players)) right before your push to confirm it’s actually an array at that point.
