Command Reference: append

Add data to the end of an array

Description

Detail

It’s worth noting that prepend and append are not data type aware. So any integers in data type aware structures will be converted into strings:

» tout: json [1,2,3] -> append: new 
[
    "1",
    "2",
    "3",
    "new"
]

Synonyms

• append
• list.append
