[Solved] Check for element in array [duplicate]

by


Both of those are doing the almost the same thing: Checking if myArray has a property called "Banana", which it doesn’t; it has keys 0,1,2, and 3, and the value at myArray[0] happens to be “Banana”.

If you want to check if a string is in an array you can use Array.prototype.indexOf:

if( myArray.indexOf("Banana") >= 0 ) {
  console.log("yes")
} else {
  console.log("no")
}
