Now Immutable.js made its way into many frontends. This challenge consists of a typical refactoring that many of us are facing now.

Start file

lines[1][1] = 'hello'
lines[2][0] = 'world'
lines[3][1] = 'whats'
lines[10][2] = 'going'
lines[12][1] = 'on'

End file

lines
	.setIn([1, 1], 'hello')
	.setIn([2, 0], 'world')
	.setIn([3, 1], 'whats')
	.setIn([10, 2], 'going')
	.setIn([12, 1], 'on')
