Delete first element from each array in javascript

Question

I have a multi dimensional array like this.

 var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']]

I want to remove all the first element to get a result like this.

var myArray = [['1','2.33','44'],['1','2.33','44'],['1','2.33','44']]

Please Help me. Thanks

Use .forEach to loop over the nested arrays and then .splice them. Splice will remove the first item in the nested array and effect the current array.

var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']];

myArray.forEach(array => array.splice(0,1));

console.log(myArray);

Base on the comment you can also use .shift() function to remove the first item.

var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']];

myArray.forEach(array => array.shift());

console.log(myArray);

You can also use .shift() instead of .splice(0,1).

You can try this

var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']];
var done = function(){
  console.log(myArray);
};
myArray.forEach(function(array){
  array.splice(0,1);
  done();
});

Output

[['1','2.33','44'],['1','2.33','44'],['1','2.33','44']];
