Capitalize the first letter each word-CodePudding

I'm trying to capitalize the first letter of each word. But it just working first word only.

html

<ion-input  [(ngModel)]="addcategory.setting.category" (ngModelChange)="transform(addcategory.setting.category)"></ion-input>

transform(value: string) {
    const inputText = value.toLowerCase().split(' ');
    console.log(inputText);
    for (var i = 0; i < inputText.length; i  ) {
      console.log(inputText.length);
      inputText[i] = inputText[i].charAt(0).toUpperCase()   inputText[i].slice(1);
      console.log(inputText[i]);
      return this.addcategory.setting.category = inputText.join(' ');
    }
  }

You can use this one-liner:

string.split(' ').map(word => word[0].toUpperCase()   word.substring(1)).join(' ');

What it does:

// splits the string at the spaces
const splitArr = string.split(' ') 

// loop over the array of words, and return your desired result
// Desired result is: capitalize the first letter and append the rest of the word.
const capitalizedArr = splitArr.map(word => word[0].toUpperCase()   word.substring(1))

// join the words from the capitalized array with a space.
const result = capitalizedArr.join(' ');

Try this:

function capitalizeFirstLetter(str) {
    const arr = str.split(" ");

    for (var i = 0; i < arr.length; i  ) {
        arr[i] = arr[i].charAt(0).toUpperCase()   arr[i].slice(1);
    }

    return arr.join(" ");
}
