'["Ford", "BMW", "Fiat"]' Inside the JSON string there is a JSON array literal: ["Ford", "BMW", "Fiat"] Arrays in JSON are almost the same as arrays in JavaScript. In JSON, array values must be of type string, number, object, array, boolean or null. In JavaScript, array values can be all of the above, plus any other valid JavaScript expression, including functions, dates, and undefined.
You can create a JavaScript array from a literal:
Example myArray = ["Ford", "BMW", "Fiat"];You can create a JavaScript array by parsing a JSON string:
Example myJSON = '["Ford", "BMW", "Fiat"]';
myArray = JSON.parse(myJSON);You access array values by index:
Example myArray[0];{
"name":"John",
"age":30,
"cars":["Ford", "BMW", "Fiat"]
}You access array values by index:
Example myObj.cars[0];You can access array values by using a for in loop:
Example for (let i in myObj.cars) {x
+= myObj.cars[i];
}Or you can use a for loop:
Example for (let i
= 0; i < myObj.cars.length; i++) {x
+= myObj.cars[i];
}
