Push one array into another [duplicate]

Question

I have two arrays as following.

var first = [['2','23','33'],['2','23','33'],['2','23','33']]

var second = ['value1','value2','value3']

Now i want to push second array into first like this.

var first = [['value1','value2','value3'],['2','23','33'],['2','23','33'],['2','23','33']]

Thanks in advance

Answer 1

Use unshift to adds element to the beginning of an array

var first = [['2','23','33'],['2','23','33'],['2','23','33']]

var second = ['value1','value2','value3']
first.unshift(second)
