Template strings: raw property

Use the raw property of tagged template strings like so s.raw

the raw property accesses the string as it was entered

function firstChar(strings) { return strings; } assert.equal(firstChar`\n`, '\\n');

raw can access the backslash of a line-break

function firstCharEntered(strings) { var lineBreak = strings.raw; return lineBreak; } assert.equal(firstCharEntered`\n`, '\\');

String.raw as a static function

concats the raw strings

var expected = '\n'; assert.equal(String.raw`\n`, expected);

two raw-templates-string-backslashes equal two escaped backslashes

const TWO_BACKSLASHES = '\\'; assert.equal(String.raw`\\`, TWO_BACKSLASHES);

works on unicodes too

var smilie = '\u{1F600}'; var actual = String.raw`\u{1F600}`; assert.equal(actual, smilie);
