grab name of every element in array javascript code example

Example 1: javascript every method

// array.every(function(elemnt)) method takes in a function 
// which evaulates each elment 
// The every method is designed to check if all the elements
// in an array meet a specific condition 
// This condition is defined within your function

let numbers = [1, 2, 3, 42, 3, 2, 4, -1];

let allPassed = numbers.every(function(element){
	return element > 0;
});

// This method returns a Boolean value
