javascript uppercase first letter
//capitalize only the first letter of the string.
function capitalizeFirstLetter(string) {
return string.charAt(0).toUpperCase() + string.slice(1);
}
//capitalize all words of a string.
function capitalizeWords(string) {
return string.replace(/(?:^|\s)\S/g, function(a) { return a.toUpperCase(); });
};How do I make the first letter of a string uppercase in JavaScript?
//1 using OOP Approach
Object.defineProperty(String.prototype, 'capitalize', {
value: function() {
return this.charAt(0).toUpperCase()+ this.slice(1).toLowerCase();
},
enumerable: false
});
function titleCase(str) {
return str.match(/\w\S*/gi).map(name => name.capitalize()).join(' ');
}
//-------------------------------------------------------------------
//2 using a simple Function
function titleCase(str) {
return str.match(/\w\S*/gi).map(name => capitalize(name)).join(' ');
}
function capitalize(string) {
return string.charAt(0).toUpperCase() + string.slice(1).toLowerCase();
