Problem with typeof

function isArray(val) {
return typeof val === ‘array’;

I have warning ‘invalid type comparison’ how to fix it? I try replace ‘array’ with Array but not sure about this solution.

Can you post more of your code? Can you show the line of code which is calling the function isArray?

there is no “array” type in javascript - arrays have type “object”

use Array.isArray to check for arrays

const a=[2,4,6]
const b={0:2, 1:4, 2:6, length:3}
typeof a // "object"
Array.isArray(a) // true
typeof b // "object"
Array.isArray(b) // false
