I am new to JavaScript and I have created this condition to check if the season is Autumn, Winter, Spring, or Summer.

Here is my JavaScript code:

1. My question is how to make this in fewer lines of code

2. How to use both uppercase and lowercase in the same code for eg: October and october

    const seasonName = prompt('entere the month name')
   
    if (seasonName == 'september') {
    console.log("The Season is Autumn.")
    }
    else if (seasonName == 'october') {
    console.log("The Season is Autumn.")
    }
    else if (seasonName == 'november') {
    console.log("The Season is Autumn.")
    }
    else if (seasonName == 'december') {
    console.log("The Season is Winter.")
    }
    else if (seasonName == 'january') {
    console.log("The Season is Winter.")
    }
    else if (seasonName == 'february') {
    console.log("The Season is Winter.")
    }
    else if (seasonName == 'march') {
    console.log("The Season is Winter.")
    }
    else if (seasonName == 'april') {
    console.log("The Season is Spring.")
    }
    else if (seasonName == 'may') {
    console.log("The Season is Spring.")
    }
    else if (seasonName == 'june') {
    console.log("The Season is Summer.")
    }
    else if (seasonName == 'july') {
    console.log("The Season is Summer.")
    }
    else if (seasonName == 'august') {
    console.log("The Season is Summer.")
    }

I like to take the following approach:

const seasonsByMonth = {
   'january': 'winter',
   'february': 'winter',
   ' march': 'winter',
   'april': 'spring',
   ...
}
const seasonName = prompt('entere the month name');
console.log(`The Season is ${seasonsByMonth[seasonName.toLowerCase()]}.`)

CodePudding user response：

Convert the input code to lower or uppercase, then compare. const seasonNameLowercase = seasonName.toLowerCase(); then use the seasonNameLowercase variable in the if conditions, or you can also use switch.

CodePudding user response：

You can use switch statement. Code is like this:

switch(seasonName) {
    case "september":
    case "october":
    case "november":
        console.log("The Season is Autumn.");
        break;
    case "december":
    case "january":
    case "february":
        console.log("The Season is Winter.");
        break;
    case "march":
    case "april":
    case "may":
        console.log("The Season is Spring.");
        break;
    case "june":
    case "july":
    case "august":
        console.log("The Season is Summer.");
        break;
}

CodePudding user response：

You could assign them as objects and use key value pairs to retrieve

// add your months as objects
const seasonObj = {
Autumn: ["september", "october", "november", ],
Spring: ["april", "may"],
summer: ["june", "july", "august"],
Winter: ["december", "january", "february", "march"]
}

function getSeason(value) {
for (const [key, val] of Object.entries(seasonObj)) {
  if(val.includes(value))
  {
  return `the Season is ${key}`
  }
}
}
const result = getSeason("april");
console.log(result)
