i'm a beginner in JS and was wondering what is the syntax of an arrow function with an if statement with a regular function such as function
getStringLength(string){
let stringLength;
if (string.length === 1){
stringLength = `La chaîne contient qu'un seul caractère`;
} else {
stringLength = `La chaîne contient ${string.length} caractères`;
}
return stringLength;
}
That would be
const getStringLength = (string) => {
let stringLength;
if (string.length === 1){
stringLength = `La chaîne contient qu'un seul caractère`;
} else {
stringLength = `La chaîne contient ${string.length} caractères`;
}
return stringLength;
}
With ternary this would look like this using an arrow function.
Note that with arrow functions you can avoid using the return keyword
const getStringLength = (string) => string.length === 1 ? `La chaîne contient qu'un seul caractère` : `La chaîne contient ${string.length} caractères`
console.log(getStringLength('a'))
console.log(getStringLength('abcdef'))You can also do it in one line
const getStringLength = (string) =>
string.length === 1 ?
`La chaîne contient qu'un seul caractère` :
`La chaîne contient ${string.length} caractères`
console.log(getStringLength('a'))
console.log(getStringLength('ab'))
