javascript if array is true code example

Example 1: 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

Example 2: check if all elements in array are true javascript

You can use `every()` array method 

let data = [ {status: true}, {status: false}, {status: true} ]
let result = data.every((i) => {
	return i.status === true
})
console.log(result) // false

let data = [ {status: true}, {status: true}, {status: true} ]
let result = data.every((i) => {
	return i.status === true
})
console.log(result) // true
