Need a simple explanation of the inject method

Question

[1, 2, 3, 4].inject(0) { |result, element| result + element } # => 10

I\'m looking at this code but my brain is not registering how the number 1

Answer 1

The code iterates over the four elements within the array and adds the previous result to the current element:

• 1 + 2 = 3
• 3 + 3 = 6
• 6 + 4 = 10
