How can I delete one element from an array by value

Question

I have an array of elements in Ruby

[2,4,6,3,8]

I need to remove elements with value 3 for example

How do I do that?<

Answer 1

I like the -=[4] way mentioned in other answers to delete the elements whose value are 4.

But there is this way:

irb(main):419:0> [2,4,6,3,8,6].delete_if{|i|i==6}
=> [2, 4, 3, 8]
irb(main):420:0>

mentioned somewhere in "Basic Array Operations", after it mentions the map function.
