Example 1: array every javascript
[12, 5, 8, 130, 44].every(elem => elem >= 10); // false
[12, 54, 18, 130, 44].every(elem => elem >= 10); // true
Example 2: js every
const exams = [80, 98, 92, 78, 77, 90, 89, 84, 81, 77]
exams.every(score => score >= 75) // Say true if all exam components are greater or equal than 75
Example 3: javascript every
const age= [2,7,12,17,21];
age.every(function(person){
return person>18;
}); //false
//es6
const age= [2,7,12,17,21];
age.every((person)=> person>18); //false
Example 4: 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
// allPassed is set to false because not all elements were greater than 0
Example 5: every in javascript
let data = [ {status: true}, {status: false}, {status: true} ]
let result = data.every((i) => {
return i.status === true
})
console.log(result) // false
Example 6: js every
function isBigEnough(element, index, array) {
return element >= 10;
}
[12, 5, 8, 130, 44].every(isBigEnough); // false
[12, 54, 18, 130, 44].every(isBigEnough); // true
