If I have an array like this
["one","two","three","hello","world","bar"]
How would I find which object in the array is "Hello"?
const arr = ["one","two","three","hello","world","bar"];
const index = arr.indexOf("hello");
console.log(index)You could use findIndex() or indexOf(). Both return the index of the item if it is in the array or -1 if it is not.
const array = ["one","two","three","hello","world","bar"]
const result = array.findIndex(item => item === "hello");
if(result === -1) console.log("Not found");
else console.log(`"hello" found at index ${result} in array: array[${result}] = ${array[result]}`);const array = ["one", "two", "three", "hello", "world", "bar"]
const result = array.indexOf("hello");
if (result === -1) console.log("Not found");
else console.log(`"hello" found at index ${result} in array: array[${result}] = ${array[result]}`);
