javascript-number and string comparison size

JavaScript often compares the size of strings, sometimes confusing, so simply comb the comparison of JavaScript strings:

    1. Number comparison    Console.log (' number comparison: ' + (< 3) ');//false    //2. String numbers and numbers are uniformly converted to numbers for comparison    console.log (' string numbers and numeric comparisons: ' + (< ' 5 ')); False    //3. When strings and numbers are compared to a non-pure number, a non-numeric string is converted to a number when it is turned to Nan, and false    is returned regardless of the size of Nan and the number comparison. Console.log (' string and number comparison: ' + (> ' flyelephant ')); False    Console.log (' string and number comparison: ' + (< ' flyelephant ') ');//false    //4. String number comparison convert to ASCII code comparison    Console.log (' String number comparison: ' + (' one ' < ' 5 ')); Fasle    console.log (' One '. charCodeAt ());//49    console.log (' 5 '. charCodeAt ());//53    //5. String comparison Convert to ASCII code to compare    Console.log (' string comparison: ' + (' Blog Park ' < ' flyelephant '));    Console.log (' Blog Park '. charCodeAt ()); 21338    console.log (' Flyelephant '. charCodeAt ());//70

From the above code we can conclude that the string comparison is more inclined to convert to a number comparison, only two operand is a string when the ASCII code conversion is compared ~
