strReplacer#replace

• str - target string to be replace.
• regexp - A RegExp object.
• iterator - A function to be invoked to create the new substring.

let content = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
let reg = /[A-Y]/g;
let str = strSplicer.replace(content, new RegExp(reg), (match)=> {
 // match is the result of RegExp(reg).exec()
 return match[0] + '-';
});
 // str: A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z

strReplacer#replaceAsync

• str - target string to be replace.
• regexp - A RegExp object.
• iteratorAsync - A function to be invoked with the new substring callback.
• done - invoked until no more substring matches by regexp in str

let content = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
let reg = /[A-Y]/g;
strSplicer.replaceAsync(content, new RegExp(reg), iteratorAsync(match, cb)=> {
 // match is the result of RegExp(reg).exec()
 cb(null, match[0] + '-');
}, (err, str)=> {
 // err: null
 // str: A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z
