'2019-02-26' == '2019-02-26'
express: '2019-02-26' == '2019-02-26' >>>>> true
`f`+`s`
express: `f`+`s` >>>>> "fs"
a +1 > b * 8
express: a +1 > b * 8 >>>>> false
a >= 0
express: a >= 0 >>>>> true
'a'+c
express: 'a'+c >>>>> "ac"
b
express: b >>>>> 2
a < 1
express: a < 1 >>>>> false
a +1 > b*8
express: a +1 > b*8 >>>>> false
a * b == 2
express: a * b == 2 >>>>> true
a - b == 0
express: a - b == 0 >>>>> false
a >= 0 && a != 0
express: a >= 0 && a != 0 >>>>> true
a == 1 && a != 0
express: a == 1 && a != 0 >>>>> true
1 > 3
express: 1 > 3 >>>>> false
1 + 2 != nil
express: 1 + 2 != nil >>>>> true
1 != null
express: 1 != null >>>>> true
1 + 2 != nil && 1 > 0
express: 1 + 2 != nil && 1 > 0 >>>>> true
1 + 2 != nil && 2 < b*8
express: 1 + 2 != nil && 2 < b*8 >>>>> true
-1 != nil
express: -1 != nil >>>>> true
-1 != -2 && -1 == 2-3
express: -1 != -2 && -1 == 2-3 >>>>> true
-1 == a*-1
express: -1 == a*-1 >>>>> true
-1 + a*-1
express: -1 + a*-1 >>>>> -2.0
