Discussion on: "for" vs. "forEach" and the value of documentation

[kip]

You can do something more to keep this code structure, just a helper variable:

function greaterThan(numbr){
    let helper = false;

    array1.forEach(function(item){
        if (item >= numbr && !helper){
            helper = true;
        };
    });

    return helper;
};

But to keep the functional style that you want with forEach and stay in simple(readable?) code:

const greaterThan = (number) => array1.some((v) => v >= number)

Sometimes exists another method in the docs to get the goal that you want...

Thank you!

some method doesn't check the condition with every element present in the array it just returns true if one element satisfies the condition.

const array = [2,3,4,5];

function  greaterThan(number) {
 return  array.some((e) => e >= number)
}


console.log( greaterThan(1)); // true

Like in above code some method only checks the condition with first element in the array so it returns true .

There is a every method in javascript, it checks the condition with every element present in the array.

const array = [2,3,4,5];

function  greaterThan(number) {
 return  array.every((e) => e >= number)
}


console.log( greaterThan(1)); // true
