In a text I use a Javascript with a line like this

format: '{point.name}',

now LME recognizes an expression. How can I tell LME that it should be ignored?

Insert a space after the opening brace and before the closing brace.

thanks, this expression will be ignored correctly, but more expressions afterwrds will be ignored too

Sorry, I don't understand the comment. Everything within the braces with spaces will be ignored by Expression Manager. Subsequent braces without spaces will be processed by EM.

Else,

Unsure it can work for javascript, but to make some doc on demo, i use HTML Entity Encode but if it's for a jason javascript object : best is to add a line feed
