Can you “dumb down” ES6 template strings to normal strings?

荒凉一梦 提交于 2019-11-26 23:35:39
问题 I have to work around the limitation of gettext to recognise ES6 template strings, and I thought about getting the "non interpolated value" of the template strings as a compilation step, in order to have only "normal" strings in the code. Basically what I would like to achieve is transform this const adjective = 'wonderful' const something = `Look, I am a ${adjective} string` console.log(something) > "Look, I am a wonderful string" into this const adjective = 'wonderful' const something =

Bergi Is there a way to programmatically construct a Template literal? No. "programmatically" and "literal" are antithetic (except you are in the realms of compilers). Template strings should better have been named interpolated

Template String As Object Property Name

Why does JavaScript not allow a template string as an object property key? For example, when I input: foo = {`bar`: 'baz'} into the NodeJS REPL, it throws a SyntaxError with "Unexpected template string" with a long stack trace. Property values are fine, however, which is not as unexpected. Similar errors happen in the browser, for example, Firebug throws a SyntaxError with "invalid property id". Template strings are allowed in "computed property names". For instance, this compiles perfectly fine in all browsers that support the syntax: var foo = { [`bar` + 1]: `baz` }; and creates the object {

I have the following code for Ecma-Script-6 template literals let person = {name: 'John Smith'}; let tpl = `My name is ${person.name}.`; let MyVar="My name is "+ person.name+"."; console.log("template literal= "+tpl); console.log("my variable = "+MyVar); The output is as follows: template literal= My name is John Smith. my variable = My name is John Smith. this is the fiddle. I tried searching for the exact difference but couldn't find it, My question is what is the difference between these two statements, let tpl = `My name is ${person.name}.`; And let MyVar = "My name is "+ person.name+".";

问题 I\'m not sure how to explain this, but when I run console.log`1` In google chrome, I get output like console.log`1` VM12380:2 [\"1\", raw: Array[1]] Why is the backtick calling the log function, and why is it making a index of raw: Array[1] ?

Usage of the backtick character (`) in JavaScript?

不问归期 提交于 2019-11-25 22:30:41
问题 In JavaScript, a backtick † seems to work the same as a single quote. For instance, I can use a backtick to define a string like this: var s = `abc`; Is there any way in which the behavior of the backtick actually differs from that of a single quote? † Note that among programmers, \"backtick\" is one name for what is more generally called the grave accent. Programmers also sometimes use the alternate names \"backquote\" and \"backgrave\". Also, on Stack Overflow and elsewhere, other common
