- 4. String Comparison inJavascript Based on The Abstract Relational Comparison Algorithm in ES5, Javascript process the string comparison in the following way. '6.1' < '11.5' '6' -> 54 '1' -> 49 It keeps moving on to the next characters of the both strings sequentially till the end of string, comparing the unicode value of the each characters. 54 < 49 It then exits after comparing different unicode value. In our case, as the unicode value of the first character from the first string is greater, the first string is greater. Hence the output is FALSE.
