javascript pushing element at the beginning of an array [duplicate]
Solution 1:
Use unshift
, which modifies the existing array by adding the arguments to the beginning:
TheArray.unshift(TheNewObject);
Solution 2:
Use .unshift()
to add to the beginning of an array.
TheArray.unshift(TheNewObject);
See MDN for doc on unshift()
and here for doc on other array methods.
FYI, just like there's .push()
and .pop()
for the end of the array, there's .shift()
and .unshift()
for the beginning of the array.
Solution 3:
For an uglier version of unshift
use splice
:
TheArray.splice(0, 0, TheNewObject);
