Category: Variables

Returns true if the searchValue string is found in the string, else returns false.

In apps you sometimes need to check if one string is contained in another string; for example if a userid contains a space or not since spaces are not allowed. includes() returns a boolean true or false and is sometimes used similarly to a boolean expression in the condition of an if, if-else, or while statement. To call the includes function you need use a variable containing a string, followed by a dot ("."), followed by the function name "includes()" with a string argument or variable of what to search for.


// See if a sentence is a question or not.
var sentence="How old are you?";

Example Original Gettysburg Address Demonstrate that includes() is case sensitive.

// Demonstrate that includes is case sensitive.
var gettysburgAddress="Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.";

Example Original Movie > Sequels Check if a movie is a sequel or not.

// Check if a movie is a sequel or not.
textLabel("movieLabelID", "Favorite Movie: ");
textInput("movieInputID", "");
onEvent("movieInputID", "change", function(event) {
  if (getText("movieInputID").includes("2") || getText("movieInputID").includes("II")) {
    write("Sequels are never as good as the original.");
  } else {
    write("I like that one also.");
