--description--

到目前为止,已经了解了如何用正则表达式来执行字符串的匹配。但有时候,并不关注匹配字母的大小写。

大小写即大写字母和小写字母。大写字母如"A""B""C"。小写字母如"a""b""c"

可以使用标志flag来匹配这两种情况。标志有很多不过这里我们只关注忽略大小写的标志——i。可以通过将它附加到正则表达式之后来使用它。这里给出使用该标志的一个实例/ignorecase/i。这个字符串可以匹配字符串"ignorecase""igNoreCase""IgnoreCase"

--instructions--

编写正则表达式fccRegex以匹配"freeCodeCamp",忽略大小写。正则表达式不应与任何缩写或带有空格的变体匹配。

--hints--

你的正则表达式应该匹配freeCodeCamp

assert(fccRegex.test('freeCodeCamp'));

你的正则表达式应该匹配FreeCodeCamp

assert(fccRegex.test('FreeCodeCamp'));

你的正则表达式应该匹配FreecodeCamp

assert(fccRegex.test('FreecodeCamp'));

你的正则表达式应该匹配FreeCodecamp

assert(fccRegex.test('FreeCodecamp'));

你的正则表达式不应该匹配Free Code Camp

assert(!fccRegex.test('Free Code Camp'));

Your regex should matchFreeCOdeCamp

assert(fccRegex.test('FreeCOdeCamp'));

你的正则表达式不应该匹配FCC

assert(!fccRegex.test('FCC'));

你的正则表达式应该匹配FrEeCoDeCamp

assert(fccRegex.test('FrEeCoDeCamp'));

你的正则表达式应该匹配FrEeCodECamp

assert(fccRegex.test('FrEeCodECamp'));

你的正则表达式应该匹配FReeCodeCAmp

assert(fccRegex.test('FReeCodeCAmp'));

--seed--

--seed-contents--

let myString = "freeCodeCamp";
let fccRegex = /change/; // Change this line
let result = fccRegex.test(myString);

--solutions--

let myString = "freeCodeCamp";
let fccRegex = /freecodecamp/i; // Change this line
let result = fccRegex.test(myString);
