How to find if any of elements within an array are within range between 50 and 99 in JavaScript?

This is given array:

var a = [2, 5, 8, 16, 35, 42, 55, 67, 89, 95, 102, 108, 112];

How to find if ANY of the elements from the array a are within range of 50 to 99? To return true if ANY of these elements are within range 50 to 99, and false if not!

How to find if ALL of the elements of this array a are within range of 50 to 99? To return true if ALL of these elements are within range 50 to 99 and false if at least one element is outside this range!

You can you some and every.

const A = [2, 5, 8, 16, 35, 42, 55, 67, 89, 95, 102, 108, 112];

console.log('#1 ', A.some(element => element > 50 && element < 99))

console.log('#2 ', A.every(element => element > 50 && element < 99))

var a = [2, 5, 8, 16, 35, 42, 55, 67, 89, 95, 102, 108, 112];

//if at least one element in the range of 50 and 99
console.log(a.filter(e => e >= 50 && e <= 99).length > 0)

//if all elements are in the range of 50 and 99
console.log(a.filter(e => e >= 50 && e <= 99).length === a.length)

You can use arrays functions some and every for this. In this solution I assumed that 50 and 99 are inclusive and they are also valid values.

How to find if ANY of the elements from the array a are within range of 50 to 99? To return true if ANY of these elements are within range 50 to 99, and false if not!

You can use .some()

a.some((x) => x >= 50 && x <= 99)

How to find if ALL of the elements of this array a are within range of 50 to 99? To return true if ALL of these elements are within range 50 to 99 and false if at least one element is outside this range!

You can use .every()

a.every((x) => x >= 50 && x <= 99)


var a = [2, 5, 8, 16, 35, 42, 55, 67, 89, 95, 102, 108, 112];


console.log(a.some((x) => x >= 50 && x <= 99));
console.log(a.every((x) => x >= 50 && x <= 99));

Array#some() and Array#every()

var a = [2, 5, 8, 16, 35, 42, 55, 67, 89, 95, 102, 108, 112];

console.log("some", a.some(value => value > 50 && value < 99));
console.log("every", a.every(value => value > 50 && value < 99));
