Some errors in the JavaScript authoritative guide (Chinese version)

I am currently learning JS, using the JavaScript authoritative guide (Chinese version), learning to find some details of the error, if my mistake, please correct

　　

1.P11------ more. "We call

The original　　

return MATH.SQRT (A * A + we call B * b);

2.P16------Canvas incorrectly written as Vanvas

The original

The 21st chapter covers the HTML-based <vanvas> tag client API, which is used for drawing arbitrary shapes.

3.P38------"5 for Friday " wrongly written as "5 for Monday"

The original

// =>5: Get Day of the week, 0 stands for Sunday, 5 for Monday

4.P39------var e = "?? "; wrongly written as var e = "E";

The original

var p = "π";         // π by 16-bit internal code 0x03c0 var e = "E";         // E is represented by a 17-bit        internal code 0x1d452 P.length             //  = 1:p contains a 16-bit value e.length             // + = 2: e UTF-16 encoded with two 16-bit values: "\UD835\UDC52"

The e referred to here should refer to the natural base??

Original

The original English is

should be translated into
