SyntaxError: missing : after property id - JavaScript | MDN
ES6 only, FYI.
If you create a property key from an expression, you need to use square brackets. Otherwise the property name can't be computed:
<code class="language-javascript">var obj = { 'b'+'ar': 'foo' };
// SyntaxError: missing : after property id</code>

Put the expression in brackets []:
<code class="language-javascript">var obj = { ['b'+'ar']: 'foo' };</code>

You can also prefix the command by a space in bash and it won't be saved to history.

I believe this only works if you have
$ export HISTIGNORE=' *'

or add the above line to bash_profile

Ralph Ubertang Ellipsis • 4 days ago −
or just read it in as a var then unset it.
