Question

I have an array

var array = ["google","chrome","os","windows","os"];

I want to delete the value "chrome" from the array without the array becoming a string. Is there a way to do this?

Answer 1

There’s no faster way than finding it and then removing it. Finding it you can do with a loop or (in implementations that support it) indexOf. Removing it you can do with splice.

Live example: http://jsbin.com/anuta3/2

var array, index;
array = ["google","chrome","os","windows","os"];
if (array.indexOf) {
  index = array.indexOf("chrome");
}
else {
  for (index = array.length - 1; index >= 0; --index) {
    if (array[index] === "chrome") {
      break;
    }
  }
}
if (index >= 0) {
  array.splice(index, 1);
}
