Convert decimal format to string with specified format in Javascript

I need to convert decimal to string in some specific format

1.0 to "+01:00"
-4.0 to "-04:00"

I have used .toString() but that is only converting to string as expected how to convert it into above format. Please suggest

    You can create a custom function to convert number to your desired format using padStart and toFixed.

    const format = num => {
  const sign = num > 0 ? '+' : '-';
  const [first, second] = num.toFixed(2).split('.');
  return `${sign}${first.replace('-','').padStart(2, '0')}:${second}`
}
console.log(format(1.0))  // "+01:00"
console.log(format(-4.0)) // "-04:00"

    const convert = (val) => {
  const plusMinus = val > 0 ? '+' : '-';
  const decimal = val.toFixed(2).replace(/./, ':').replace(/^-/, '');
  const prefixedZero = val < 10 && val > -10 ? '0': '';
  return `${plusMinus}${prefixedZero}${decimal}`
}

console.log(convert(1.0))
console.log(convert(-4))
console.log(convert(0))
console.log(convert(-10))
   console.log(convert(10))
