use expect to check for true value in an array javascript code example

Example: javascript check if any value in array is true

let boolArray1 = [true, false, false]
let boolArray2 = [false, false, false]

boolArray1.some(x => x);  // true
boolArray2.some(x => x);  // false

// Example of using a function to evaluate array
let numberArray = [1, 2, 3, 4, 5];
let oddNumbers = [1, 3, 5, 7, 9];

// checks whether an element is even
const even = (element) => element % 2 === 0;

numberArray.some(even);  // true
oddNumbers.some(even);   // false
