Answers for "is there a noop in javascript"

Javascript

Better Array check with Array.isArray Because arrays are not true array in JavaScript, there is no simple typeof check. No problem! Use the method Array.isArray to checkâ€¦

var colors=["red","green","blue"];

if(Array.isArray(colors)){
    //colors is an array
}
