How to check if a list contains a string in javascript? -

-

this question has answer here:

how can test if string "orange" without quotes, exists in list such 1 below, using javascript?

var suggestionlist = ["apple", "orange", "kiwi"];

edit: question different "how check if array.." because newbies me don't know list of items @ first glance "array". newbies going search term "list".

indexof() default use in such cases. 

if( suggestionlist.indexof("orange") > -1 ) {     console.log("success"); }

.indexof() returns position in array (or string) of found element. when no elements found returns -1.
