loop errors in angular

In angular I've tying to loop my given errors and show them in alert but it doesn't work, I've read and tried different solutions such as using lenght or lenght+1 etc. none of them seem to work.

Data

{name: Array(1), email: Array(1), password: Array(1)}
email: ["The email field is required."]
name: ["The name field is required."]
password: ["The password field is required."]
__proto__: Object

Code

error => {
        let errors = error.error.errors;
        console.log(errors); //return result above
        for (var i = 0; i < errors.length; i++) {
          this.alertService.presentToast(errors[i]);
        }
      },

any idea?

You can simply use this

Object.keys(errors).forEach(key => {
    alert(errors[key][0]);
});

Hi there are two ways to print the error messages. Hope it may help full for you

1.

for (let [key, value] of Object.entries(errors)) {
    console.log(value[0]);
}

2.

for (let [key, value] of Object.entries(errors)) {
    for(let msg of value) {
        console.log(msg);
    }   
}
