How to create a function that will display number according to specific range. ex from 1-29 show 1,-CodePudding

I need to create a function based on input value. Example: if we enter number from 1-29 then show 1, from 30-59 show 2, from 60-89 show 3 and so on...

I'm new to this and can't figure out how to make that. Please help...

CodePudding user response：

You can try something like this to make it more dynamic.

function getRange(num) {
    if (num <= 0) {
        return 'Invalid input';
    }
    let rangeSize = 30;
    let range = Math.floor(num/rangeSize) 1;
    return range;
}

Demo

function getRange(num) {
    if (num <= 0) {
        return 'Invalid input';
    }
    let rangeSize = 30;
    let range = Math.floor(num/rangeSize) 1;
    return range;
}

console.log(getRange(29))
console.log(getRange(30))
console.log(getRange(59))
console.log(getRange(62))
