transformedDays = days.map(day => day[0].toUpperCase() + day.substr(1))
Give this a shot:
function makeFirstLetterUppercase(text) {
return text.charAt(0).toUpperCase() + text.slice(1);
}
To easily capitalize the first letter of each day, you can iterate over the days in a loop with this code snippet:
const days = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday'];
for (const day of days) {
console.log(day[0].toUpperCase() + day.substr(1));
}Hopefully this solution is beneficial
capitalizeFirstLetter(string);
Traditional approach:
const days = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday'];
var result = [];
for(var i = 0; i < days.length; i++){
result.push(days[i].charAt(0).toUpperCase() + days[i].substring(1));
}
console.log(result);By utilizing the function map along with the regex pattern /(.?)/, you can easily replace the first captured letter with its uppercase version.

var output = months.map(m => m.replace(/(.?)/, (letter) => letter.toUpperCase()));
